Answer:
D. Stored Energy
Explanation:
Think of it this way, potential energy is the energy dependant on the objects position (PE=mgh). Say you are on a diving board (my fave example), when you are standing on the edge about to jump you have the potential to fall or move because you can go from a) the top to b) the pool. When you are in the pool you're already there, so there is no more potential. Remember that, once you jump, you have kinetic energy (KE=1/2mv^2), or the energy of motion and no longer PE.
