Momentum, Energy and Collisions
... Introduction For two interacting objects, if there is no net external force then we expect the total momentum of the system to be conserved. In contrast, energy is only conserved when certain types of forces are exerted between the objects. Collisions are classified as elastic (kinetic energy is con ...
