Question

a roller coaster at an amusement park goes from the top of a tall hill to the bottom. during this time, the roller coaster a gains both potential and kinetic energy b loses both potential and kinetic energy c loses kinetic energy and gains potential energy d loses potential energy and gains kinetic energy

Explanation:

Potential energy is related to height and kinetic energy to speed. As the roller - coaster goes from the top of a tall hill to the bottom, its height decreases (losing potential energy) and its speed increases (gaining kinetic energy).

Answer:

A. loses potential energy and gains kinetic energy
