![]() Free Fall 3D JS Model
written by
Wolfgang Christian
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. ![]() ![]() This source code zip archive contains an XML representation of the Free Fall 3D JavaScript Model. Unzip this archive in your EJS workspace to compile and run this model using EjsS ver 5.1. Although EjsS is a Java program, it creates a stand alone JavaScript program from this source code. download 34kb .zip Last Modified: November 21, 2014
