Question

pendulum kinetic energy multiple-choice question which example below shows kinetic energy? a boulder about to roll down the mountain a pendulum about to be released a rock rolling down the mountain

Explanation:

Kinetic energy is the energy of motion. A boulder about to roll and a pendulum about to be released have potential energy (stored energy due to position). A rock rolling down the mountain is in motion, so it has kinetic energy.

Answer:

C. A rock rolling down the mountain (assuming the options are labeled A, B, C as per the order: A. A boulder about to roll down the mountain, B. A pendulum about to be released, C. A rock rolling down the mountain)
