... In physics, energy is defined as the capacity of a physical system to do work. This can be measured by the amount of work done. Scientists often relate this to the amount of force needed to move an object of a given mass a given distance. For example, if you inflated your balloon to a diameter of tw ...

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.
