What is sound energy?

Back

Sound energy is the energy produced by vibrating sound waves. It travels through air, water, and solids.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a ball held at a height has gravitational potential energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.
