Kinetic and Potential Energy Review

How will the ball's potential and kinetic energy change as it rolls down the hill?

• The ball's potential and kinetic energy will both decrease.

• The ball's potential and kinetic energy will both increase.

• The ball's potential energy will decrease, and its kinetic energy will increase.

• The ball's potential energy will increase, and its kinetic energy will decrease.

Based on the picture, hill X is higher than hill Y because if hill Y were higher, the car would

• require less kinetic energy to go over hill Y.

• come to a complete stop at the top of hill Y.

• require additional mass to go over hill Y.

• require additional kinetic energy to go over hill Y.

Which statement best describes the results of their investigation?

• The less potential energy the band has, the more kinetic energy is transferred, and the farther the band travels.

• The more kinetic energy the band has, the more potential energy is transferred, and the farther the band travels.

• The more potential energy the band has, the more kinetic energy is transferred, and the farther the band travels.

• The less kinetic energy the band has, the more potential energy is transferred, and the farther the band travels.
