Suppose the skater is at the highest point in the jump and she pauses in air for a moment. What are the relative amounts of the skater’s kinetic energy and gravitational potential energy at that point?

• all kinetic energy, no gravitational potential energy

• half kinetic energy, half gravitational potential energy

• no kinetic energy, all gravitational potential energy

• no kinetic energy, no gravitational potential energy

Which of the following statements about the kinetic energy and potential energy of the skater are true?

• As the skater rolls up the side of the half-pipe, the skater gains kinetic energy.

• The skater has the most gravitational potential energy at the bottom of the half-pipe.

• Gravitational potential energy transforms into kinetic energy when the skater rolls down the side of the half-pipe.

• The skater transfers gravitational potential energy to the skateboard.

Two cars are driving down the road. Car A has a mass of 1,100 kg and is moving at 20 m/s. Car B is has a mass of 1,000 kg and is moving at 30 m/s. Which car has more kinetic energy and why?

• car A because it has more mass and almost the same speed as car B

• car B because it has a greater speed and almost the same mass as car A

• car A because it has a lower speed and almost the same mass as car B

• car B because it has less mass and almost the same speed as car A
