I believe that the mechanical energy would transform from starting out as kinetic, the reaching the top it would be potential, then go back to kinetic as it is falling back down.
I'm not 100% sure that this is right but if I had to take a guess this is what I would say.
The size of the force varies inversely as the square of the distance between the two charges. Therefore, if the distance between the two charges is doubled, the attraction or repulsion becomes weaker, decreasing to one-fourth of the original value
I don't have research to back it up, but exercise is working out. Fitness is taking care of your body, that includes working out and things like eating right.
