The Simple Harmonic Oscillator JS Model displays the dynamics of a ball attached to an ideal spring.  The spring is initially stretched and the ball has zero initial velocity.  The initial position of the ball can be changed by click-dragging the ball when the simulation is paused.

The Simple Harmonic Oscillator JS Model was developed using the Easy Java/JavaScript Simulations (EjsS) version 5.  It is distributed as a ready-to-run html page and requires only a browser with JavaScript support.  This model runs on tablets.
