Front

What are the two main types of energy?

Back

Kinetic energy (energy of motion) and potential energy (stored energy).

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion.

Front

What is potential energy?

Back

Potential energy is stored energy that has the potential to do work.

Front

What is an example of kinetic energy?

Back

A moving car or a running person.

Front

What is an example of potential energy?

Back

A book on a shelf or a drawn bow.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases and its kinetic energy increases.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of kinetic and potential energy in an object.

Front

What is sound energy?

Back

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

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter.
