Question

which of the following best explains why a ball rolling down a ramp has kinetic energy? it is at rest and storing energy; it has a high position above the ground; it is generating sound waves; it is in motion

Explanation:

Kinetic energy is the energy of motion. A ball rolling down a ramp is in motion, so it has kinetic energy. The first option describes potential energy (stored energy at rest), the second also relates to potential energy (due to position), and the third is about sound energy, not the main reason for kinetic energy here.

Answer:

D. It is in motion (assuming the blue option was mis - numbered and the correct one is the last with "It is in motion")
