Question

which of the following has kinetic energy?

a. a horse in the starting gate before a race

b. a swimmer standing on a diving board

c. a basketball player sitting on the bench

d. a gymnast doing a cartwheel

Explanation:

Kinetic energy is the energy an object has due to its motion. Option A: The horse is at rest (in the starting gate before the race starts), so no kinetic energy. Option B: The swimmer is standing (at rest) on the diving board, so no kinetic energy. Option C: The basketball player is sitting (at rest) on the bench, so no kinetic energy. Option D: The gymnast is doing a cartwheel, which involves motion, so the gymnast has kinetic energy due to that motion.

Answer:

D. A gymnast doing a cartwheel
