Use this diagram to answer the question.

An object is lifted into the air and dropped. Which statement best describes the object's energy as it falls through the air from the stationary position at height X?

• At height X, the energy is potential, which changes to kinetic as the object falls.

• At height X, the energy is kinetic, which changes to potential as the object falls.

• At height X, the energy is potential and kinetic, and the object loses potential energy as it falls.

• At height X, the energy is potential and kinetic, and the object loses kinetic energy as it falls.
