The Mass and Spring Simple Harmonic Oscillator mobile JavaScript model illustrates the forces and dynamics of a simple oscillator. This simulation uses the accelerometer on mobile devices to read the direction of the gravitation field g. You may, of course, need to lock the orientation of your screen to maintain a fixed view as you rotate your device. For use on computers without an accelerometer or for classroom use, the demo mode simulates a gravitational field in the y-direction.
The Mass and Spring Simple Harmonic Oscillator mobile JavaScript Model was developed using version 5 of the Easy Java Simulations (EJS 5) modeling tool. Although EJS is a Java program, EJS 5 creates stand alone JavaScript programs that run in almost any browser.

Source Code Documents
The Horizontal SHO with Accelerometer source code archive contains an XML representation Horizontal SHO with Accelerometer for use with EJS. Unzip this archive in your EJS workspace to compile and run this model using EJS 5. Although EJS is a Java program, EJS 5 creates a stand alone JavaScript program from this source code.
