Front

What type of energy is produced by the vibrations of a drum?

Back

The vibrations of a drum produce sound energy.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total energy of all the particles in an object.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a book on a shelf has potential energy because it can fall.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion. Any moving object has kinetic energy.

Front

What is nuclear energy?

Back

Nuclear energy is the energy stored in the nucleus of an atom. It can be released during nuclear reactions.

Front

What is sound energy?

Back

Sound energy is the energy produced by vibrating objects and is transmitted through air, water, or solids.
