Unit 8: Energy Test Review

When the rollercoaster reaches the BOTTOM of the hill, all the energy is converted to ___. Ignoring friction.

• Thermal Energy

• Kinetic Energy

• Gravitational Potential Energy

• Nuclear Energy

Answer explanation

The Law of Conservation of Energy states that Energy is transferred from one form into another.

In the case of the roller coaster, the greatest GPE is found at the highest point and the greatest KE is found at the lowest point.

Arrange in order from least to greatest potential energy.

• A, B, C, D

• D, B, C, A

• B, C, D, A

• A, D, C, B

Answer explanation

The least amount of GPE is found at the lowest position and the greatest amount of GPE is found at the greatest height.
