Masses and Springs

In this interactive simulation adapted from the University of Colorado's Physics Education Technology project, hang various masses from different springs and see the kinetic, potential, and thermal energy of each spring system. You can even slow time or move your demonstration to another planet.

Sound

This interactive simulation, adapted from the University of Colorado's Physics Education Technology project, illustrates sound waves. Adjust the frequency and amplitude to see and hear how the waves change.

Vibration Patterns on a Chladni Plate

In this interactive activity adapted from the University of Southern California, investigate how sound vibrations cause patterns to form in sand on a metal plate.
