Answer:
Potential Energy is stored energy or energy of position (gravitational). The object isn't moving. For example, a ball being held is potential energy because the object isn't moving but it has the potential of turning into kinetic energy.
Kinetic Energy is the energy of motion. For example, running. You are moving, and there is clear action and activity
It is the gravitational force pulling on something
It seems that you have missed the necessary options for us to answer this question so I had to look for it. But anyway, here is the answer.
