[tex]E_1+ E_2+ \cdot\cdot\cdot+ E_n= C[/tex]

where [itex]E_1[/itex], [itex]E_2[/itex], [itex]E_n[/itex] are all the different kinds of energy in a system and C is a constant? In other words, energy can change from one form to another or from one object to another but in a given isolated system the total remains constant.

I started that a little facetiously but we use "kinetic energy+ potential energy= constant" in simple problems all the time.
