Pendulum Motion Model
written by Andrew Duffy
The Pendulum Motion Model shows the motion of a simple pendulum. You can change the mass of the pendulum bob, the length of the string, the acceleration due to gravity, and the initial position of the pendulum. You can then see the resulting motion of the pendulum, as well as see bar graphs of the energy and plots of the pendulum's angular position, angular speed, and angular acceleration as a function of time.

The Pendulum Motion model was created using the Easy Java Simulations (EJS) modeling tool.  It is distributed as a ready-to-run (compiled) Java archive.  Double clicking the ejs_bu_pendulum.jar file will run the program if Java is installed.

Please note that this resource requires at least version 1.5 of Java (JRE).
