If the atoms of a body have mass and are jiggling around they have their own kinetic energies. But if they move in a way that the center of mass of the body moves, then the body gains energy. This energy can come from work if I push the body. Kinetic energy means mass with speed. But speed needs...

and that proton and electron won't form an atom?

what does unstable mean here?

neutrons don't have electric charge

Then what is kinetic energy?

the electromagnetic interaction can only move things that have an electrical charge, right?
