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. WebThe change in gravitational potential energy is directly proportional to mass, gravitational field strength, and change in height. K = 1 2 m v 2 K = \dfrac{1}{2} ... There are a few …
