Step by step this climber slowly creeps up the side of a 1000-m-tall rock face The secret to clinging like a fly on a wall is a force called friction This force is exerted on the climber at each place where he touches the rock Friction balances gravityrsquos downward pull on the climber and keeps him from sliding down the wall

Describe three examples of pushing or pulling on an object In each case how did the object move

A Long Way DownA Long Way Down

An objectrsquos motion changes if the forces acting on the object are unbalanced

LESSON 1 Combining Forces

Can you feel the forceImagine pushing a chair that has wheels on its legs Now imagine push-ing the chair with a friend sitting in it Is there a difference in how hard you would have to push

Procedure 1 Set your textbook on the table in front of

you and push it so that it moves at a constant velocity

2 Put at least one more book on top of your textbook and push the stack of books at a constant speed

Think About ThisImagine performing the experiment on ice instead of on the table Do you think the pushes needed to keep the books moving across ice would be different than the pushes needed to move them across the table Explain your answer

Combining ForcesWhen more than one force acts on an object the

combined effect is caused by the sum of all applied forces

Real-World Reading Connection Think about all the things you push or pull every day You might push on computer keys pull open a door push a shopping cart or pull a heavy backpack from the floor onto your shoulders What happens when more than one push or pull acts on an object

What is a forceA push or a pull is called a force Forces are always exerted by

one object on another object In Figure 1 a hand exerts a force on the boards and on the bow string The hand pushes on the boards and pulls on the bow string What other pushes or pulls do you observe around you

Contact ForcesWhen you press the keys on a computer keyboard your fin-

gers exert a force on the keys This force can be exerted only when your fingers are touching the keys A force that is exerted only when two objects are touching is a contact force A contact force can be small such as the force you exert to push a pencil across a sheet of paper or large such as the force exerted by a tow truck as it pulls a car along a street Both of the forces shown in Figure 1 are contact forces

Lesson 1 bull Combining Forces 89

Noncontact ForcesWhen you jump up in the air you are pulled back to the

ground even though nothing seems to be touching you The sky-diver in Figure 2 is also being pulled downward even though there seems to be nothing touching him Forces can be exerted by one object on another even though they arenrsquot touching each other The force pulling you and the skydiver down to Earth is the gravi-tational force exerted by Earth This force is a noncontact force A noncontact force is a force that one object exerts on another when they are not touching The magnetic force that two magnets exert on each other is also an example of a noncontact force Noncon-tact forces include the gravitational force the electric force and the magnetic force

Force is a VectorRecall from the previous chapter that the velocity of an object is

a vector A vector has a size and a direction A velocity vector is represented by an arrow that points in the direction of motion The length of the arrow represents the objectrsquos speed A force also is a vector that can be represented by an arrow The direction of the arrow is the direction of the push or the pull The length of the arrow represents the size or strength of the force The arrow becomes longer as the size of the force increases

The unit for the size of a force is the newton (N) A force with a size of 1 N is a small force The force needed to lift a half-stick of butter or a fast-food hamburger is about 1 N To lift a 2-L bottle of water requires a force of about 20 N Figure 3 shows some exam-ples of force vectors

Combining ForcesSuppose you are trying to move a heavy piece of furniture such

as the dresser shown in Figure 4 You donrsquot have to push as hard if a friend helps and you both push together in the same direction When more than one force acts on an object the forces combine The combination of all the forces acting on an object is called the net force How forces combine depends on the direction of the forces applied to an object

What is the net force acting on an object

Combining Forces in the Same DirectionIf you and a friend both push on the same side of the dresser

the forces that you both exert are in the same direction When the forces acting on an object are in the same direction they add together as shown in Figure 4 to form the net force When you both push on the dresser in the same direction the net force is in the same direction in which both of you push

Because forces are vectors it is necessary to specify a reference direction to be able to combine forces For example you could choose ldquoto the rightrdquo as the positive reference direction in Figure 4 Then both forces would be positive For example suppose you push with a force of 200 N to the right and your friend pushes with a force of 100 N to the right Then the net force is 200 N 100 N 300 N Because the net force is a positive number its direction is to the right The dresser will slide as if it were being pushed by one person exerting a force of 300 N to the right

Figure 4 Describe the net force acting on the dresser

ACADEMIC VOCABULARYspecify(verb) to name or state in detailThe store clerk asked the cus-tomer to specify the size and color of the shirt he wanted

Figure 4 When forces in the same direction combine the net force is also in the same direction The size of the net force is the sum of the two forces

Combining Forces in Opposite DirectionsSuppose you and a friend push on the dresser as shown in

Figure 5 Then the two forces are in opposite directions If ldquoto the rightrdquo is the positive reference direction then one force is positive and the other is negative For example a force of 200 N is exerted to the right and a force of 100 N is exerted to the left Then the force exerted to the left is a negative number The net force equals 200 N 100 N 100 N Because the net force is a positive num-ber it is being exerted to the right

Unbalanced and Balanced ForcesIn the two examples just discussed the net force on the dresser

was not zero When the net force on an object is not zero the forces are unbalanced forces Figure 6 shows an example in which the net force on the dresser is zero When the net force on an object is zero the forces on the object are called balanced forces

Figure 5 When two forces in oppo-site directions com-bine the net force is in the same direc-tion as the larger force The size of the net force is the dif-ference in the sizes of the two forces

Figure 6 The net force on the dresser is zero so the two forces on the dresser are balanced forces

How do forces affect motion

What happens when you push or pull on an object When you pull your backpack upward its motion changes as it moves upward How-ever when you push against a brick wall the wall doesnrsquot move The motion of an object changes when it changes speed or changes direction Whether the motion of an object changes depends on whether the forces acting on it are balanced or unbalanced

Unbalanced Forces and MotionIf you kick a soccer ball you apply a contact

force to the ball You exert a force when your foot is in contact with the ball The force you exert causes the ball to change speed and direction When you kick the ball the force exerted by your foot combines with other forces on the ball to form the net force on the ball Figure 7 shows the net force on the soccer ball as you kick it Because the net force on the ball is not zero the forces on the ball are unbalanced The unbalanced forces on the ball caused its velocity to change This is true for any object The velocity of an object changes if the forces acting on it are unbalanced

Balanced Forces and MotionImagine two people push on a dresser in

opposite directions with forces of the same size You probably know what happensmdashthe dresser doesnrsquot move In this case the net force is zero and the forces on the dresser are bal-anced When the forces on an object are bal-anced the motion of the object doesnrsquot change

Even when the forces acting on an object are balanced the object can be moving Figure 8 shows the forces acting on a skydiver after the parachute opens The downward force of grav-ity on the skydiver is balanced by the upward force exerted by the parachute Because the forces are balanced the velocity of the skydiver doesnrsquot change The skydiver floats downward at a constant speed

Figure 7 The net force on the ball is unbalanced causing the velocity of the ball to change

Figure 8 The forces on the skydiver are balanced so the velocity of the skydiver doesnrsquot change

Infer the net force on the skydiver

Newtonrsquos First Law of MotionIsaac Newton a scientist who lived from 1642 to 1727 explained

how forces cause motion to change He developed three rules that are now called Newtonrsquos laws of motion Newtonrsquos first law of motion describes how an object moves when the forces acting on it are balanced According to Newtonrsquos first law of motion if the net force on an object is zero an object at rest remains at rest or if the object is moving it continues to move in a straight line with con-stant speed In other words if the net force on an object is zero the velocity of the object doesnrsquot change

What is Newtonrsquos first law of motion

InertiaAccording to the first law of motion the motion of an object

changes only when unbalanced forces act on it The tendency of an object to resist a change in its motion is called inertia Inertia explains the motion of the crash-test dummies in Figure 9 When the car hits the barrier the barrier exerts an unbalanced force on the car This unbalanced force changes the motion of the car and makes it stop However without a safety belt that exerts an unbal-anced force on the dummies their motion doesnrsquot change Each dummy keeps moving until it hits the steering wheel the dash-board or the windshield

Mass and Change in MotionThe size of the net force needed to cause a certain change in

motion depends on the objectrsquos mass Imagine trying to stop a bicycle or a car both traveling at the same speed You wouldnrsquot have to push very hard to stop the bicycle However the car might have 100 times more mass than the bicycle A much larger net force is needed to cause the same change in motion as the bicycle

What have you learnedIn this lesson you read that forces acting on an object can be

added together to determine the net force acting the object Since forces are vectors it is important to include the size and direction of the force when adding them together If the forces add to a zero net force the forces are balanced and the motion of the object does not change Newtonrsquos first law of motion states that the motion of an object will not change if the net force is zero If the net force is not zero the motion of the object will change

Lesson 2 bull Types of Forces 97

The Law of Universal GravitationIn the seventeenth century Isaac Newton

was thinking about gravity He wondered if the motion of falling objects and the motion of the Moon around Earth are caused by the same type of force Newton found that it was gravity that pulled objects downward and caused the Moon to orbit Earth In 1687 he published the law of universal gravitation (yew nuh VER sul bull gra vuh TAY shun) that showed how to calcu-late this force According to the law of universal gravitation all objects are attracted to each other with a force that depends on the masses of the objects and the distance between them

Gravity Mass and DistanceFigure 11 shows how the size of the force of

gravity depends on the mass of the objects and the distance between them The gravitational force becomes stronger as the mass of one or both of the objects increases The force becomes weaker as the distance between the objects increases

How does the force of gravity between two objects change as they move closer together

Table 1 compares the force of gravity exerted on a 70-kg person by a textbook the Sun and Earth The force exerted by the text-book is extremely small because its mass is small The force exerted by the Sun is also small because it is so far away Table 1 shows that only Earth is close enough and massive enough to exert a noticeable gravitational force on the person

Figure 11 Gravitational force depends on the masses of the objects and the distance between them

Weight and MassWhen you stand on a bathroom scale what are you measuring

You are measuring the pull of Earthrsquos gravitymdasha force The weight of an object is the gravitational force exerted on an object Recall that mass is the amount of matter in an object and does not change with location Mass is not a vector because there is no direction involved Weight however is a force vector it has a size and direction Your weight is a force that always points toward the center of Earth

Relationship Between Weight and Mass The size of an objectrsquos weight at the surface of Earth is proportional to the objectrsquos mass For example if the mass of an object doubles the weight of the object doubles If the mass is reduced by half the objectrsquos weight is reduced by half

What is the relationship between mass and weight

Weight and Mass High Above Earth In addition to mass the distance between objects also affects weight Figure 12 shows how weight changes with height above Earth An astronaut on the surface of Earth may have a mass of 55 kg and a weight of 540 N directed toward the center of Earth While in orbit the astronautrsquos mass doesnrsquot change However the gravitational force on her would be smaller because she is farther from Earth As a result her weight would be reduced to about 500 N

FrictionImagine pushing a book away from you across a table As the

book slides it slows down and then stops The force causing the book to slow down is a type of friction Friction (FRIHK shun) is a force that opposes the movement between two surfaces in con-tact The size of the friction force depends on the types of surfaces in contact The frictional force usually becomes smaller as the sur-faces become smoother

Static FrictionSuppose you push on a heavy box as in Figure 13 and the box

doesnrsquot move Then the forces on the box are balanced The force you exert on the box is balanced by a force acting on the box in the opposite direction This force is called static friction Static friction is the force between two surfaces in contact that keeps them from sliding when a force is applied The static friction force is exerted on the bottom of the box where it touches the floor

As you push harder the box still doesnrsquot move This means that the force of static friction has increased to balance the force you apply as shown in Figure 13 The force due to static friction increases as you increase the force you apply However there is a limit to the size of the static friction force between two surfaces If you push hard enough your applied force will be greater than the maximum static friction force Then the forces on the box are no longer balanced and the box begins to move

Static friction balances the force applied to the box

SCIENCE USE V COMMON USE staticScience Use at rest or having no motion The fluid in the pipe was static Common Use noise produced in a radio or a television After the radio was dropped all we could hear was static

WORD ORIGINfriction from Latin fricare means to rub

Static friction increases to balance the larger force applied to the box

Figure 15 In an air-hockey game the puck floats on a layer of air so that friction is almost eliminated As a result the puck moves in a straight line with nearly constant speed after itrsquos been hit


Sliding Friction When the force pushing on the box is larger

than the maximum static friction force the box begins to slide When the box is sliding a different frictional force acts on the box This force is sliding friction The size of sliding fric-tion is usually smaller than static friction The direction of sliding friction is always opposite to the velocity of the sliding object as shown in Figure 14

Figure 14 Compare the size of the applied force and sliding friction

Unlike static friction the size of sliding fric-tion does not change if you push on the box harder As long as the object is sliding the force of sliding friction is the same If the force you apply is greater than sliding friction the box speeds up as it slides If the force you apply is equal to sliding friction the box slides with a constant velocity

How would the velocity of the book change if the applied force were equal to the sliding friction force

Motion Without FrictionAt one time people thought that forces

caused motion In other words a object would move only if there were unbalanced forces act-ing on it For example once you stop pushing on a skateboard it slows down and stops You might think that the skateboard stops because there are no forces acting on it However it stops because friction acts on it On Earth friction is present whenever something moves Without friction the skateboard would con-tinue to move in a straight line with constant speed According to the first law of motion instead of causing motion unbalanced forces cause changes in motion When friction is greatly reduced as in Figure 15 objects move with a nearly constant velocity

Figure 14 The force of sliding friction is always opposite to the motion of the sliding box

Figure 17 The force applied to the rubber band by the fingers is a tension force that causes the rubber band to exert an elastic force

Elastic ForcesIn Figure 16 a diver standing on the end of the diving board

bends the board downward Because he is not moving the forces acting on him must be balanced One of the forces acting on him is the downward pull of Earthrsquos gravity This means there must be an upward force acting on him that balances the downward force of gravity This force is exerted on the diver by the diving board and is called an elastic (ih LAS tik) force An elastic force is the force exerted by a material when it is stretched or compressed The diving board exerts an upward elastic force on the diver when it is bent downward

TensionThink about stretching a rubber band as shown in Figure 17

You apply a force to the rubber band and you can feel the rubber band pulling back as it is stretched The force exerted by the rub-ber band is an elastic force caused by the stretching of the rubber band The force you apply to the rubber band that stretches it is a tension (TEN shun) force A tension force is a pulling force applied to an object that can make the object stretch A tension force applied to an object causes the object to exert an elastic force that pulls back in the opposite direction The size of this elastic force equals the size of the tension force

CompressionWhen you squeeze a rubber ball the ball changes shape You

can feel the ball push back on your hand as you squeeze The rub-ber ball exerts an elastic force on your hand when you squeeze it The force you exert on the ball is a compression force A compres-sion force is a squeezing force applied to an object that can make an object shrink The elastic force exerted by the ball is equal to the compression force you exert on the ball

Normal ForcesThe glass sitting on the table in Figure 18 is not moving so the

forces acting on it are balanced The table exerts an upward force on the glass called the normal force that balances the downward pull of gravity A normal force is a force exerted by an object that is perpendicular to the surface of the object The upward normal force exerted by the table balances the downward force of gravity on the glass

The normal force exerted by the table is an elastic force The weight of the glass pushing down on the table is a compression force This causes the material in the table to be squeezed together As a result the table pushes back upward on the glass Table 2 summarizes the forces discussed in this lesson

Figure 18 The forces on the glass are balanced because the table exerts an upward normal force on the glass

Identifying Forces on an Object

More than one force can act on an object at the same time These forces can also be acting in different directions For example the force of gravity acting on a box sliding on a floor is downward The sliding friction force is hori-zontal parallel to the floor The forces acting in the vertical direction can cause an objectrsquos vertical motion Horizontal forces can change an objectrsquos horizontal motion

Forces in the Horizontal DirectionSuppose you push a book at a constant speed

across a flat table as shown in Figure 19 The book is moving in a horizontal direction with a constant velocity as you push it According to the first law of motion this means that the forces on the book must be balanced

You apply a force on the book in the hori-zontal direction Because the book is sliding a sliding friction force is acting on the book The direction of this force is horizontal in the opposite direction to the force you apply The size of this force must be equal to the size of your push Then the horizontal forces on the book are balanced As a result the horizontal motion of the book doesnrsquot change The book moves in a straight line with constant speed

Why are the horizontal forces acting on the book balanced

Forces in the Vertical DirectionAs the book slides across the table it doesnrsquot

move up or down This means that the forces in the vertical direction must be balanced as shown in Figure 19 The force of gravity pulls the book downward The table exerts an upward normal force on the book For these forces to be balanced the upward normal force must have the same size as the downward force of gravity Because the vertical forces are bal-anced the vertical motion of the book doesnrsquot change In this case the book doesnrsquot move in the vertical direction

LESSON 2 Review


What have you learnedThere are different types of forces Gravity is an attractive force

between two objects The size of the gravitational force depends on the masses of the objects and the distance between them Friction is a force that always opposes the sliding motion of two surfaces in contact An elastic force results when an object is stretched or compressed These forces can act on an object at the same time It is often useful to further group the forces into horizontal and ver-tical forces so you can predict how the motion of the object will change in the horizontal and vertical directions

Unbalanced Forces and VelocityWhen an objectrsquos speed or direction of motion changes you

know that there is an unbalanced force acting on the object How do unbalanced forces affect objects at rest and in motion

Unbalanced Forces on an Object at RestThe ball on the left side of Figure 20 is at rest What two

forces act on the ball to result in a zero net force The down-ward force resulting from gravity is balanced by the upward normal force exerted by the hand However when the normal force is removed the forces on the ball are unbalanced Then the velocity of the ball increases in the downward direction as it falls In other words the ball accelerates in the downward direc-tion This is the same direction as the unbalanced force on the ball When an unbalanced force acts on an object at rest the object accelerates in the direction of the unbalanced force

Figure 20 Identify the unbalanced force acting on the ball

Figure 20 The ball accelerates in the direction of the unbalanced force acting on it

Lesson 3 bull Unbalanced Forces and Acceleration 107

Unbalanced Forces on an Object in MotionUnbalanced forces can also change the motion of objects that

are already moving Whether the unbalanced force causes the object to speed up or slow down depends on the direction of the unbalanced force in relation to the direction of motion

Speeding Up When does an unbalanced force cause an object to speed up If an object is moving a net force applied in the same direction the object is moving causes the object to speed up For example in Figure 21 the net force is in the same direction as the sledrsquos velocity This makes the sled speed up and its velocity increase

The net force on a ball falling to the ground is downward This force is in the same direction the ball is moving Because the net force on the ball is in the same direction as the ballrsquos velocity the ball speeds up as it falls

Slowing Down If the net force on an object is in the direction opposite to the objectrsquos velocity the object slows down In Figure 21 the force of sliding friction becomes larger when the boy puts his feet in the snow The net force on the sled is the com-bination of gravity and sliding friction When the sliding friction force becomes large enough the net force is opposite to the sledrsquos velocity This causes the sled to slow down

If an object is slowing down what is the relationship between the objectrsquos velocity and the net force act-ing on the object

Speeding Up

Figure 23 The force exerted by the string is always perpendicular to the ballrsquos velocity It also always points to the center of the circle

Describe how the ballrsquos velocity is changing


Unbalanced Forces and Direction of Motion

The direction of motion can also change when the forces on an object are unbalanced The ball in Figure 22 is moving in a straight line before it hits the rail The rail then exerts an unbalanced force on the ball causing its direction of motion to change The rail affects the ballrsquos motion only when it is in contact with the ball

Figure 23 shows a ball that is tied to a string and swung in a horizontal circle This type of motion is called circular motion The velocity of the ball is changing as it moves because the direc-tion of its motion is changing The unbalanced force acting on the ball is the tension force exerted by the string This force is called the centripetal (sen TRIH put ul) force In circular motion the centripetal force is the force that is perpendicular to the velocity and toward the center of the circle The force exerted by the string is the centripetal force that keeps the ball moving in a circle

Newtonrsquos Second Law of MotionUnbalanced forces can cause an object to speed up slow down

or change direction When an object changes speed or direction its velocity changes and the object is accelerating In other words unbalanced forces cause an object to accelerate According to Newtonrsquos second law of motion the acceleration of an object equals the net force divided by the objectrsquos mass The acceleration is in the same direction as the net force Newtonrsquos second law of motion can be written as this equation

Newtonrsquos Second Law Equation

acceleration (in ms2) net force (in N)

mass (in kg)

a F m

In this equation force is measured in newtons and mass is mea-sured in kilograms When force is measured in newtons and mass in kilograms the unit for acceleration is metersecond2 This unit is the same as meter(seconds times seconds)

Newtonrsquos Second Law and the Net ForceNewtonrsquos second law of motion explains how balanced and

unbalanced forces affect an objectrsquos motion When the forces are balanced the net force is zero According to the second law of motion this means that the objectrsquos acceleration is zero Then the velocity is constant and the objectrsquos motion doesnrsquot change

If the forces on the object are unbalanced then the net force is not zero According to the second law of motion the acceleration is not zero and the velocity of the object changes In other words only unbalanced forces cause the motion of objects to change

If the acceleration is not zero are the forces on the object balanced or unbalanced

Newtonrsquos Second Law and Planetary MotionThe planets including Earth move around the Sun in nearly

circular paths This means that the planets are accelerating because their direction of motion is always changing According to the second law of motion there must be an unbalanced force act-ing on Earth and the other planets Isaac Newton realized that this force was the gravitational force exerted by the Sun Figure 24 shows how the gravitational force exerted by the Sun keeps Earth moving in a circular path

Recall that a centripetal force keeps an object moving in a circle The gravitational force exerted by the Sun is the centripetal force that keeps the planets moving around the Sun You will read more about gravity and the motion of the planets in Chapter 11

Newtonrsquos Third Law of Motion

How high can you jump Think about the forces acting on you when you jump Because you are accelerating there must be an unbalanced force acting on you What causes this force You might think itrsquos your legs and feet that push you upward Yoursquore partly right

According to the Newtonrsquos third law of motion when one object exerts a force on a second object the second object exerts an equal force in the opposite direction on the first object In the case of jumping as in Figure 25 the feet exert a force on the ground The ground then pushes upward on the feet causing the jumper to accelerate upward

Force Pairs The forces two objects exert on each other are

called force pairs The forces in a force pair act in opposite directions and are always equal in size

If force pairs are equal in size and act in opposite directions why donrsquot they cancel each other out Remember that the forces in force pairs act on different objects When you jump you exert a force on Earth and Earth exerts a force on you One force in the force pair acts on Earth and the other force acts on you These forces do not result in a zero net force because they act on different objects Equal and opposite forces cancel out only if they act on the same object Figure 26 shows an example of a force pair One force acts on the boat and the other force acts on the person

Figure 26 Explain why the force pair does not result in a zero net force

Action and ReactionIn force pairs one force of the force pair is

sometimes called the action force and the other force is the reaction force When you push on a wall the action force is the force you exert on the wall The reaction force is the force exerted by the wall on you For every action force there is a reaction force that is equal in size but opposite in direction

Figure 25 According to the third law of motion the ground exerts the upward force that pushes the jumper into the air

Figure 26 The force pair is the force exerted by the person on the boat and the force the boat exerts on the person

Table 3 Newtonrsquos Laws of Motion

Law Statement of Law Example

Newtonrsquos first law of motion

An object at rest will remain at rest unless acted on by an unbalanced force An object in motion will continue moving at a constant velocity unless acted on by an unbalanced force

The forces acting on a book at rest on a table are balanced so the bookrsquos motion does not changeThe forces acting on a skydiver with an open parachute are balanced so the skydiver falls in a straight line at a constant speed

Newtonrsquos second law of motion

The size of the acceleration of an object is equal to the net force on the object divided by its mass The acceleration is in the same direction as the net force

A skydiver jumping out of a plane accelerates toward the ground as gravity pulls her down

Newtonrsquos third law of motion

When one object exerts a force on another object the second object exerts a force on the first object that is equal in size but opposite in direction

When you push on a wall with a force of 100 N the wall pushes back on you with a force of 100 N

Figure 27 Newtonrsquos laws of motion describe how the forces acting on this basketball player affect his motion


Applying Newtonrsquos LawsNewtonrsquos laws of motion describe how forces

affect the motion of any object For example the motion of the jumping basketball player in Figure 27 can be explained by the laws of motion

When you push down on the ground the third law of motion says that the ground pushes up on you This force combines with the downward force of gravity to form the net force acting on you If you push down hard enough the direction of the net force becomes upward According to the second law of motion you accelerate upward

When you are in the air the downward force due to gravity is in the direction opposite to your motion This causes you to slow down until you reach the top of your jump Then as you start mov-ing downward gravity is in the same direction as you are moving so you speed up as you fall

Why do you speed up when you fall

When you hit the ground the upward force exerted on you by the ground brings you to a stop Then the forces on you are balanced and you remain at rest Table 3 and Figure 28 provide more examples of how Newtonrsquos laws of motion explain objectsrsquo motion

Newtonrsquos Laws in Sports

Figure 28The motion of people balls and other objects during sports activities can be explained by Newtonrsquos laws of motion According to the first law an object in motion moves with a constant speed in a straight line unless acted upon by an unbalanced force If an object is at rest it stays at rest unless acted upon by an unbalanced force According to the second law an object accelerates in the direction of the net force The third law can be stated this waymdashfor every action force there is an equal and opposite reaction force

NEWTONrsquoS SECOND LAW As Michelle Wie hits a golf ball she applies a force that causes the ball to move in the direction of that forcemdashan example of the second law

NEWTONrsquoS FIRST LAW The diver doesnrsquot move with a constant velocity because the force of gravity on the diver is unbalanced

NEWTONrsquoS THIRD LAW Newtonrsquos third law applies whenever objects exert forces on each other Here a gymnast pushes downward on the bars The bars push back on the gymnast with an equal force

LESSON 3 Review


What have you learnedIn Lesson 1 you read that unbalanced forces cause the motion of

an object to change In this lesson you read about how forces cause motion to change An object accelerates when it changes speed or direction According to Newtonrsquos second law of motion the accel-eration of an object equals the net force divided by the objectrsquos mass The acceleration is in the same direction as the net force The third law of motion says that forces are always exerted in pairs This means that when you push on a door the door pushes on you with a force of the same size in the opposite direction

Comparing Mass and Weight

ProblemWhat is the difference between mass and weight Weight is a measure of the gravitational force on an object Earthrsquos gravita-tional pull on an object decreases as the object gets farther from Earth When astronauts orbit Earth their weight is less than when they are standing on the ground However the mass of an astro-naut doesnrsquot change when the astronaut gets farther from Earth The mass of an object is the amount of matter that makes up the object Unlike weight the mass of an object does not depend on where the object is located

Form a Hypothesis

Review the results from this chapterrsquos laboratory investigations

Form a hypothesis about the relationship between the mass and the weight of an object As mass increases or decreases how does the weight of an object change

Collect Data and Make ObservationsMake a Plan1 Read and complete a lab safety form2 As a group decide upon the materials you will need to test

your hypothesis Include any safety equipment you need to collect or safety procedures you need follow to ensure the safety of your group members

3 Devise an experiment to test your hypothesis Be specific List the steps of your experiment in logical order State exactly how you will use your equipment and what you will do during each step

4 Copy the data table on the next page into your Science Jour-nal Be certain your table contains enough rows to record the results of all your planned trials

5 Have one group member read your entire experiment aloud to the group to make certain you have all the necessary materials and that your experimental steps are in logical order and can be easily followed


2d Students know how to identify separately the two or more forces that are acting on a single static object including gravity elastic forces due to tension or compression in matter and friction9a Plan and conduct a scientific

investigation to test a hypothesis9d Recognize the slope of the linear

graph as the constant in the relationship y kx and apply this principle in interpreting graphs constructed from data

Isaac Newton Bestselling Author

Newtonrsquos three laws of motion were first published in 1687 in a book called The Mathematical Principals of Natural Philosophy Originally the book was in Latin and today it is known as the Principia the shortened form of its Latin title It is one of the most influential scientific books ever pub-lished The Principia also included Newtonrsquos discussion of the law of universal gravitation and how gravity caused the observed motions of the planets and their moons

What keeps a bridge from falling down Without tension and compression traveling in and out of San Francisco would be a lot harder Tension and compression are the forces that keep suspension bridges like the Golden Gate Bridge standing The thick horizontal cables strung over the tops of the orange towers are under tension because they are anchored into the ground The towers are put under compression because most of the weight is transferred to the towers through the vertical suspender cables

Lesson 1 Combining Forces

When more than one force acts on an object the combined effect is caused by the sum of all applied forcesbull A force is a push or a pull Forces are described by vectors that

show the forcersquos magnitude and direction

bull The net force is the sum of all forces acting on an object

bull If the net force is zero the forces are balanced If the net force is not zero the forces are unbalanced

bull If the forces on an object are balanced the motion of the object does not change

bull Unbalanced forces change the objectrsquos speed or direction of motion

bull Newtonrsquos first law of motion states that if the net force on an object is zero the motion of the object will not change

bull balanced force (p 91)bull contact force (p 88)bull force (p 88)bull net force (p 90)bull Newtonrsquos first law of motion (p 93)bull noncontact force (p 89)bull unbalanced force (p 91)

Lesson 2 Types of Forces

There are different types of forces that act on objectsbull Gravity is an attractive force between all objects that have mass

bull Friction forces push parallel to sliding surfaces opposing the motion of the surfaces

bull Compression and tension forces cause an object to be compressed or stretched

bull compression force (p 101)bull elastic force (p 101)bull friction (p 99)bull gravity (p 96)bull law of universal gravitation (p 97)bull normal force (p 102)bull tension force (p 101)bull weight (p 98)

Lesson 3 Unbalanced Forces and Acceleration

Unbalanced forces cause accelerationsbull Unbalanced forces cause objects to accelerate

bull An unbalanced force will cause an object to speed up slow down or change direction

bull Newtonrsquos second law states that the acceleration of an object equals the net force on the object divided by the objectrsquos mass The acceleration is in the direction of the net force

bull Newtonrsquos third law of motion states that all forces come in pairs When an object exerts a force on a second object the second object exerts a force equal in size but opposite in direction on the first object

Can you feel the forceImagine pushing a chair that has wheels on its legs Now imagine push-ing the chair with a friend sitting in it Is there a difference in how hard you would have to push

Procedure 1 Set your textbook on the table in front of

you and push it so that it moves at a constant velocity

2 Put at least one more book on top of your textbook and push the stack of books at a constant speed

Think About ThisImagine performing the experiment on ice instead of on the table Do you think the pushes needed to keep the books moving across ice would be different than the pushes needed to move them across the table Explain your answer
