Multiple Select

Which of the following are forms of energy that can be found in a pinball machine?

• Mechanical energy

• Sound energy

• Electromagnetic energy

• Chemical energy

Multiple Choice

Why is the chemical energy of a battery considered potential energy and not kinetic energy?

• Because it is stored and not in motion

• Because it is moving rapidly

• Because it is related to temperature

• Because it is a form of sound energy
