Which example best distinguishes kinetic energy from potential energy?

• A. Kinetic energy is energy of motion (a moving baseball); potential energy is stored energy due to position (a drawn bow).
• B. Kinetic energy is stored energy; potential energy is energy of motion.
• C. Both energies are the same with different names.
• D. A drawn bow has kinetic energy only.

Answer: (D)

Energy comes in two main forms here: kinetic energy, the energy of motion, and potential energy, energy stored due to position. When something is moving, like a baseball in flight, its energy is kinetic. When something is held in a stretched or compressed state, like a drawn bow, the energy is stored as potential energy in the bow’s elastic structure. The bow isn’t moving, so it doesn’t have kinetic energy yet; it’s storing energy that will become kinetic once you release it. When released, that stored energy is converted into kinetic energy of the arrow and the moving parts. So the drawn bow best illustrates stored energy at work (potential energy), while a moving object illustrates energy of motion (kinetic energy).
