Energy and Energy Transfer Review

The diagram shows cars moving on a roller coaster track. At what location will the cars have the highest potential energy?

• 1

• 2

• 4

• 6

The illustration shows an athlete pole vaulting into the air. At which point is the gravitational potential energy converted to kinetic energy?

• when the athlete is running to begin vault

• when the athlete begins to go upwards

• when the athlete begins to fall

• when the athlete hits the mat

The diagram above shows two toy cars on a ramp. Which statement below is true?

• Car X had the greatest potential energy.

• Car Y had the greatest potential energy.

• Both cars had the same potential energy.

• Knowing which car had the greatest potential energy is impossible.

Which choice best describes the energy transferred from the bowling ball to the pins in the image above?

• kinetic to potential

• potential to kinetic

• electric to potential

• thermal to potential

A 20-kg ball and a 50-kg ball rest at the top of a ramp. Which statement best describes the potential energy of the balls?

• The 20-kg ball has the greater potential energy because it has less inertia.

• They have the same potential energy because their positions are the same.

• The 50-kg ball has the greater potential energy because it has the greater mass.

• They have the same potential energy because gravity has the same effect on each one.

A child picks a ball up from the ground, then places it on a table. The ball rolls on the table’s surface. Which statement is true?

• The ball has both kinetic and potential energy.

• The ball does not have kinetic or potential energy.

• The ball has kinetic energy but no potential energy.

• The ball has potential energy but no kinetic energy.

A toy car is released at the top of an inclined plane. How does the car’s energy change as it rolls down the inclined plane?

• Both its kinetic energy and potential energy increase.

• Both its kinetic energy and potential energy decrease.
