The motions of objects after they collide can be determined from their previous motions if the forces
Question:
The motions of objects after they collide can be determined from their previous motions if the forces acting during the collision are known. In most collisions, however,these forces are not known.The law of conservation of momentum must hold during any collision in which only internal forces act. As such,it can be used to predict the results of a collision even if the details of the interaction are unknown.When two objects collide and rebound such that both kinetic energy and linear momentum are conserved, the collision is said to be elastic. When two objects stick together after a collision, the collision is said to be completely inelastic. In this case the out come of the collision can be determined from the initial values alone because the objects stick together and move with a common velocity after the collision.The lab is about the conservation of momentum during elastic and inelastic collisions.
QUESTION: Explain how a physical experiment could be devised which would demonstrate the principles of this simulation. What type of apparatus would be needed and how could the relevant variables be measured?
