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.

Collisions on an Air Track

In this interactive activity adapted from the University of Toronto, observe the effect of mass on momentum in elastic and inelastic collisions.

Energy in a Roller Coaster Ride

See potential energy convert to kinetic energy in this interactive activity from WGBH that shows a roller coaster in action.

Energy Transfer in a Trebuchet

On NOVA, a team of carpenters, timber framers, engineers, and historians recreate a medieval throwing machine called a trebuchet. This adapted video segment explores how understanding energy transfer informs their design.
