The Free Fall 3D JavaScript Model displays the three-dimensional dynamics of a ball dropped near the surface of Earth onto a platform. The initial conditions for the ball are zero initial velocities in the x, y, and z directions. The coefficient of restitution for the ball's collision with the platform is less than one. We often use this simple model in EjsS workshops since it is is a good test for WebGL support. Drag the mouse over the scene to rotate it. Then, click the Play/Pause button.
The Free Fall 3D JavaScript Model was developed using the Easy Java/JavaScript Simulations (EjsS) version 5.1. It is distributed as a ready-to-run html page and requires only a browser or tablet with JavaScript and WebGL support.
