The Block Sliding On An Incline Plane mobile JavaScript model illustrates the forces and dynamics of a block sliding on a surface. 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 Block Sliding On An Incline Plane mobile JavaScript Model was developed by Wolfgang Christian 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.
