<span>The law of conservation of energy states that energy can change from one form into another, but it cannot be created or destroyed. Or the general definition is: The totalenergy of an isolated system remains constant over time. ... A device that demonstrates the Law of Conservation of Mechanical Energy and Momentum.</span>
