A fan transforms electrical energy into mechanical energy.

Front

What are the three types of energy produced by a television?

Back

A television transforms electrical energy into light energy, thermal energy, and sound energy.

Front

What is an example of energy transformation in nature?

Back

Photosynthesis in plants transforms solar energy into chemical energy.

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like food or batteries.

Front

What is mechanical energy?

Back

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

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter, often felt as heat.
