We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. Legal. WebThis is a result of the law of conservation of energy, which says that, in a closed system, total energy is conserved—that is, it is constant. Using subscripts 1 and 2 to represent initial and final energy, this law is expressed as. K E 1 + P E 1 = K E 2 + P E 2. Either side equals the total mechanical energy. john b. wells caravan to midnight 7/16/22
