Purpose: To show that momentum is conserved in a closed system by illustrating the conservation of momentum in an elastic collision and an inelastic collision. Method: If momentum is conserved in a closed system, the total momentum of the system before collision should equal the total momentum of the system after the collision. Strobe photos will be used in the calculations that will prove that momentum is conserved.1.) Elastic collision: A strobe photo will be used that shows a large glider smashing into a smaller glider which is initially at rest. This will cause the smaller glider to move and the large glider will continue to move also. 2.) Inelastic collision: A strobe photo will be used that shows a glider smashing into another glider which is initially at rest. When they collide the two gliders will stick together and will move.-The masses, distances and times will be measured in order to calculate the momentums of the systems before and after collision occurs.
