(10 points). What is the difference between Conservation Laws, Law of Conservation of Linear Momentum, and the Conservation of Energy?

The conservation laws state that the total magnitude of a system’s physical property energy, momentum or charge remains unchanged even when then there are changes of such property between the system components. The Conservation laws are the Law of Conservation linear momentum, Law Conservation of energy, Laws Conservation angular momentum and the Law of Conservation of charge. The Law of Conservation of Linear Momentum, states that when the resultant external force acting on a system of several bodies is zero as the linear momentum of the system is constant, while the Conservation of Energy states energy is not created or destroyed, b
