What is friction?

Back

Friction is a force that opposes motion between two surfaces that are in contact. It can produce heat.

Front

What is sound energy?

Back

Sound energy is the energy produced when an object vibrates, causing air (or another medium) to vibrate and create sound waves.

What color absorbs the most heat?

Back

Black absorbs the most heat because it absorbs all wavelengths of light.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object. It is the energy associated with the motion and position of an object.
