... At maximum displacement, the oscillating object is momentarily A stopped while it changes direction, but the spring restoring force is at a maximum (F = -kx). Momentum is conserved (p = mv). Since the total mass is greater, D then the combined velocity must be less. Total momentum increases, so an e ...

Conservation of energy
In physics, the law of conservation of energy states that the total energy of an isolated system remains constant—it is said to be conserved over time. Energy can be neither created nor be destroyed, but it transforms from one form to another, for instance chemical energy can be converted to kinetic energy in the explosion of a stick of dynamite.A consequence of the law of conservation of energy is that a perpetual motion machine of the first kind cannot exist. That is to say, no system without an external energy supply can deliver an unlimited amount of energy to its surroundings.
