Which of the following best describes the roller coaster’s energy as it moves from the top of the coaster to the bottom of the coaster?

• Both potential and kinetic energy decreases at the same time.

• The potential energy is decreased as it is converted into kinetic energy, making the roller coaster go faster.

• The potential energy decreases as the kinetic energy decreases.

• The kinetic energy stays the same while the potential energy is constantly changing.
