Understanding Energy Types and Concepts

What type of energy is associated with the motion of large objects?

• Potential energy

• Kinetic energy

• Thermal energy

• Electric potential energy

Which of the following is an example of elastic potential energy?

• A book on a shelf

• A stretched rubber band

• A moving car

• A hot cup of coffee

Explain why a system that includes the Earth and a falling ball possesses both kinetic energy and gravitational potential energy.

• Because the ball is moving and the Earth provides a gravitational field.

• Because the ball is stationary and the Earth is moving.

• Because the ball is moving and the Earth is not part of the system.

• Because the ball is stationary and the Earth provides a gravitational field.

If a spring is stretched further, what happens to the elastic potential energy stored in the spring?

• It decreases

• It remains the same

• It increases

• It disappears

A charged particle is moved across an electric field produced by another charged particle. Describe the type of energy stored in this scenario and explain how the distance moved affects the energy stored.

• Thermal energy; the energy stored decreases with distance.

• Electric potential energy; the energy stored increases with distance.

• Kinetic energy; the energy stored remains constant with distance.

• Gravitational potential energy; the energy stored decreases with distance.
