A bicycle rider is traveling up a hill. When the rider reaches the top of the hill, she stops to rest. Then she travels down the hill. The diagram shows the rider in the three different positions. Which of these correctly describes the potential energy and the kinetic energy of the bicycle rider?

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

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

• When the rider goes down the hill, her potential energy increases, and her kinetic energy decreases.

• As the rider reaches the bottom of the hill, her kinetic energy and her potential energy decrease.

The drawing shows two identical airplanes at an air show. The airplanes are flying at the same speed. Airplane W is flying 50 m higher than Airplane X. Which statement best describes the energy of the two airplanes?

• Airplane W has a greater kinetic energy than Airplane X.

• The two airplanes have the same gravitational potential energy but different kinetic energies.

• Airplane X has more gravitational potential energy than Airplane W.

• The two airplanes have the same kinetic energy but different gravitational potential energies.
