Starting from newton's second law, explain how a collision that is free from external forces conserves momentum. in other words, explain how the momentum of the system remains constant with time. newton's second law states that the acceleration of each object, which is proportional to each object's change in momentum, is proportional to the sum of the forces on the object. in the absence of external forces,
