"Energy" is a book-keeping device. It was noted pretty early on in physics that in simple collisions, two quantities mass*velocity and 1/2 * mass* velocity 2 stayed the same which made them easy to use- one was called "momentum" and the other "kinetic energy". It was observed that the speed of an object (and so it's kinetic energy ... funny baby shower theme
