Amplitude

This interactive activity adapted from the University of Utah's ASPIRE Lab shows how a pendulum's amplitude changes as you set it swinging from different distances from its axis, and how the amplitude of a sound wave changes as you adjust the volume.

Booming Sands

This video segment, adapted from NOVA scienceNOW, presents basic concepts of physics behind "booming" sand dunes. See how surface tension affects potential and kinetic energy and how it all works together to create sound.
