Potential Energy
... The higher something is from the surface of the Earth, the greater it’s potential energy. This is because it has more room to move. You can calculate the Potential energy of something: PE = mass x height Key Point: Things sitting up high have more potential energy than things sitting on the ground. ...

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.
