How does Dr. Hewitt define Potential Energy?

•Extra energy
•Energy that might or might not be there
•Energy of motion
•Energy of position
•Potent energy

In order to do work, the force vector must be question 1 options: in a different direction than the acceleration vector. in a different direction than the displacement vector. in the same direction as the displacement vector and the motion. in the same direction as the acceleration vector.
