Question

practice it!
which word is used to describe the energy of motion?
kinetic energy
light energy
sound energy
potential energy

Explanation:

Kinetic energy is the energy an object has due to its motion. Light energy is related to electromagnetic radiation (like from the sun). Sound energy is from vibrating objects creating sound waves. Potential energy is stored energy (e.g., due to position). Since the question asks for energy of motion, kinetic energy fits.

Answer:

kinetic energy
