PendahuluanKonsep Fisika yang sering kita jumpai dalam kehidupan sehari-hari adalah gerak manusia

berjalan, planet berputar, pohon tumbang. Seluruh alam semesta bergerak.

Setiap gerak didefinisikan sebagai perubahan posisi relatif terhadap titik acuan tertentu. Namun

dalam kehidupan sehari-hari kita sering menggunakan bumi (tanah) sebagai titik acuan umum

Pengertian Jarak Dan Perpindahan

- Jarak didefinisikan sebagai panjang seluruh lintasan yang dialami benda

- Perpindahan adalah panjang lintasan lurus antara posisi awal dengan posisi akhir

- Jarak hanya memiliki nilai sedangkan perpindahan memiliki nilai dan arah gerak.

Untuk memperjelas perbedaan antara jarak dan perpindahan, diilustrasikan suatu benda

bergerak 70 meter ke timur kemudian berbalik ke barat sejauh 30 meter. Jarak (distance) yang

ditempuh benda di atas adalah 100 meter ditunjukkan oleh garis putus-putus, sedangkan

perpindahannya (displacement) 40 meter, ditunjukkan garis sambung, ke arah timur.

Untuk menyelidiki apakah sebuah benda melakukan GLB atau tidak dapat digunakan

sebuah alat yang disebut pewaktu ketik atau ticker timer dan hasil percobaannya

Rumus Gerak Lurus Beraturan

Seandainya gerak benda pada Gambar tersebut membutuhkan waktu 20 sekon, kelajuan

orang tersebut adalah 5 m/s, sedangkan besar kecepatannya 2 m/s. Bagaimanakah hal ini

diperoleh?

Jarak (distance) yang ditempuh benda di atas adalah 100 meter ditunjukkan oleh garis

putus-putus, jadi kelajuannya = jarak / waktu = 100 m / 20 = 5 m/s. sedangkan perpindahannya

(displacement) 40 meter, ditunjukkan garis sambung, ke arah timur, jadi kecepatannya =

perpindahan / waktu = 40 m / 20 s = 2 m/s.

Dari ilustrasi tersebut, kita dapat merumuskannya :

v = st atau s = v.t

Dimana :

v = Kecepatan(m/s)

s = Perpindahan(m)

t = Waktu(sekon)

SimulasiSimulasi ini dibuat dengan software Matlab yang diproduksi oleh Mathworks Corp. kami

berusaha membuatnya dengan tools-tools yang ada pada matlab, kami menggunakan GUIDE

(GUI Builder).

Dalam modul ini terdapat beberapa komponen yaitu:

1. Komponen Text

2. Komponen Edit yang jumlahnya 12, diantaranya adalah:

a. 2 edit untuk input data, dan

b. 10 edit untuk hasil

3. 1 Komponen Panel

4. 2 Komponen Tombol

a. Tombol “Hitung”

b. Tombol “Grafik”

5. 2 Komponen Axes

a. Axes untuk Grafik 2 dimensi

b. Axes untuk Grafik 3 dimensi

Langkah – LangkahDalam kasus ini kita membuat suatu simulasi dengan bantuan MATLAB terdapat 3 file yaitu:

1. gerak.m

Berisi tentang source code yang digunakan dalam pembuatan simulasi

2. gerak.fig

menampilkan interface / GUI (Graphical User Interface) seperti hasil perhitungan dan

grafik.

3. gerak.asv

Nah, untuk menjalankan simulasi ini ada hal yang harus dilakukan terlebih dahulu yaitu:

1. Buka Matlab Simulink terlebih dahulu

2. Setelah itu, dibagian pojok kiri bawah terdapat tombol Start versi Matlab

3. Lalu pilih “MATLAB”

4. Lalu akan muncul dialog seperti berikut

5

5. Bila file belum ada dalam daftar klik tombol “Browse” dan pilih file yang akan dibuka

dengan extension file .fig

Program ini disertakan ke dalam CD bila ingin membukanya double klik file ‘gerak.fig’

maka akan muncul window Matlab, disebelah kiri terdapat panel ‘Current Directory’

Lalu pilih file ‘gerak.fig’ maka akan muncul Program Simulasi Gerak Lurus Beraturan
