Define gravitational potential energy.

• energy due to an object being stretched or compressed

• energy an object possesses because of its position

• energy that relies on motion

• energy that is stored

Define elastic potential energy.

• energy due to an object being stretched or compressed

• energy an object possesses because of its position

• energy that relies on motion

How are kinetic and potential energy different?

• Kinetic energy relies on motion, while potential energy is stored energy.

• Kinetic energy is stored energy, while potential energy relies on motion.

• Kinetic energy and potential energy are the same.

• Kinetic energy and potential energy are unrelated.

You are playing dodgeball in PE. You lift the ball from the floor towards your body (Figure A) and reach backwards before throwing it (Figure B). When does the ball have the most potential energy?

• The ball has the most potential energy in Figure A.

• The ball has the most potential energy in Figure B.

• The ball has the same potential energy in both Figure A and Figure B.

• The ball has no potential energy.

Tom built a model rocket. He launched the rocket from the stand using a burst of air. The rocket flew 25 feet into the air. How is the rocket's potential energy (sitting on the stand) related to the rocket's kinetic energy (flying in the air)?

• The rocket's potential energy is unrelated to its kinetic energy.

• The rocket's potential energy is equal to its kinetic energy.

• The rocket's potential energy is converted into kinetic energy.

• The rocket's potential energy is stored in the air.
