Isaac travels up a hill on his bicycle. When he reaches the top of the hill, he stops to get a drink of water. Then Isaac travels down the hill. The diagram shows Isaac at the three different positions. Which of these correctly describes the potential energy and the kinetic energy of the ride?

• When the rider is at the top of the hill, the potential energy is the greatest and his kinetic energy is the least.

• As the rider moves up the hill, his kinetic energy increases, and his potential energy decreases.

• As the reaches the bottom of the hill, his kinetic energy and his potential energy increases.

• As the rider reaches the bottom of the hill, his kinetic energy and his potential energy decreases.

Aaron's bowling ball had rolled down the lane getting faster and faster. Which statement is true?

• The bowling ball will continue to roll down the lane with the same potential and kinetic energy.

• The bowling ball is gaining more potential energy from Aaron's force.

• Aaron's ball's potential energy is changing to kinetic energy.

• The bowling ball will quickly lose kinetic energy as it rolls down the lane.
