The Easy Java Simulations Modeling and Authopring Tool is needed to explore the computational model used in the Uniform Circular Motion and SHM model.

This is the full index of Easy Java Simulations (EJS) by author Andrew Duffy, created for first-semester introductory physics.  EJS is a modeling tool developed by the Open Source Physics project.

Multimedia tutorial provides extensive background support on simple harmonic motion through video, Flash animations, informative text, diagrams, and graphs.
