Web Reference: Let’s examine how doing work on an object changes the object’s energy. If we apply force to lift a rock off the ground, we increase the rock’s potential energy, PE. Concepts of work, kinetic energy and potential energy are discussed; these concepts are combined with the work-energy theorem to provide a convenient means of analyzing an object or system of objects moving between an initial and final state. Energy goes from one storage to another, or goes to heat: Heat is a type of energy, too. In fact the total amount of energy stays the same: Energy can't be created or destroyed. This is called Conservation of Energy: energy just gets transformed and the total stays constant. Energy is lost to a system when it leaves it.
