Sep 18, 2015 · When we drop the small mass, the change in height of the small mass can be measured, as well as the velocity of the glider-mass system. This will allow the computation of the sum of kinetic and potential energies before and after the mass falls and verify (or dismiss!) the law of the conservation of mechanical energy as a useful concept. Recall from the purpose, that in its simplest terms, the law of conservation of mass states that matter can be neither created nor destroyed. Therefore, because matter is composed of atoms that are unchanged in a chemical reaction, mass must be conserved, as well as the number and types of atoms in a chemical equation.
