Question

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 1

D

Step-by-step explanation:

Kinetic energy means the energy of motion. Answer choices A, B, and C are all examples of things that are not moving or have potential energy, meaning that it could be converted to kinetic energy but is not right now. However, a swing moving back and forth is motion, meaning that it has kinetic energy. Hope this helps!
