A robust, yet easy-to-use model that simulates the motion of a simple pendulum. Provides real-time graphs of KE/PE, angular acceleration, angular velocity, and free-body diagrams.

This is a set of packaged materials for middle school use, all designed for use with the Open Source Physics Pendulum Energy Model. A pendulum simulation is viewed alongside bar graphs that show changing levels of kinetic and potential energy. Air resistance is ignored in this simulation.
