Question

when a ball drops from the roof of a building, it speeds up as it falls. what energy transformation is happening?
a. kinetic energy to gravitational potential energy
b. gravitational potential energy to kinetic energy
c. gravitational potential energy to nuclear energy
d. light energy to sound energy

Explanation:

At the roof, the ball has gravitational potential energy due to its height. As it falls and speeds up, this potential energy is converted into kinetic energy which is energy of motion.

Answer:

B. Gravitational potential energy to kinetic energy
