notes on "Kinetic vs. Potential Energy."
... Nuclear Energy: energy related to the structure of atoms. Whereas electrons are on the outside of an atom’s nucleus, the nucleus is made up of protons and neutrons. The nucleus of an atom contains a huge amount of potential energy. Protons all have the same charge and tend to push away from each ot ...

Conservation of energy
In physics, the law of conservation of energy states that the total energy of an isolated system remains constant—it is said to be conserved over time. Energy can be neither created nor be destroyed, but it transforms from one form to another, for instance chemical energy can be converted to kinetic energy in the explosion of a stick of dynamite.A consequence of the law of conservation of energy is that a perpetual motion machine of the first kind cannot exist. That is to say, no system without an external energy supply can deliver an unlimited amount of energy to its surroundings.
