select the correct answer. which of the following is an example of kinetic energy? a. a boy resting on a park bench b. a book sitting on a shelf c. a rubber band stretched as far as it can go d. a swing moving back and forth

Answer

Brief Explanations:

Kinetic energy is the energy of motion. A swing moving back and forth is in motion. A boy resting on a bench, a book on a shelf, and a stretched rubber band (which has elastic potential energy) are not in motion.

Answer:

D. a swing moving back and forth
