What are the four main types of energy?

Back

The four main types of energy are thermal, chemical, mechanical, and electromagnetic.

Front

What is thermal energy?

Back

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

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like food and fuel.

Front

What is mechanical energy?

Back

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

Front

What is electromagnetic energy?

Back

Electromagnetic energy is a form of energy that travels through space as waves, including light, radio waves, and X-rays.

What is an example of energy transformation in digestion?

Back

In digestion, chemical energy from food is transformed into mechanical energy for movement.

Front

What type of energy does a battery-operated radio use?

Back

A battery-operated radio transforms chemical energy from the battery into electrical energy and then into sound energy.

Front

What device transforms electrical energy into mechanical energy?

Back

A fan transforms electrical energy into mechanical energy to create airflow.
