The law of conscrvation of energy states that (1) the internal energy of a system is constant (2) the heat content of the system is constant (3) cnergy is neither created nor destroyed (4) there is an equivalence between energy and mass
Energy is always conserved for an isolated system. However, this chapter begins by stating that the energy of motion is only sometimes invariant, even for an isolated system. How can total energy be conserved while energy of motion is not?
