The Pendulum with Moving Support mobile JavaScript Model illustrates the forces and dynamics of a pendulum attached to a moving support. This simulation uses  the accelerometer on your mobile device to read the proper acceleration as measure by the mobile device. A force body (free body) diagram showing the pendulum rod force (blue), the gravitational force (black), and the force of friction (green) can also be shown. Users set the initial angle in radians and angular velocity in radians/second and you can adjust the viscous damping (friction) coefficient when the simulation is paused.

The Pendulum with Moving Support 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.
