Law of conservation of energy states that the total energy of an isolated system in a given frame of reference remains constant—it is said to be conserved over time. Energy can neither be created nor destroyed; rather, 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. In technical terms, conservation of energy can be rigorously proven by the Noether theorem to be a direct consequence of continuous time translation symmetry.
