Conservation of momentumAim: demonstrate that momentum is conserved in a closed system by illustrating the conservation of momentum in an elastic collision and in an inelastic collision.Method: if momentum is conserved in a closed system, the total momentum of the system before the collision should be equal to the total momentum of the system after the collision. The stroboscopic photos will be used in calculations that will demonstrate that momentum is conserved. 1.) Elastic Collision: A stroboscopic photo will be used showing a large glider crashing into a smaller glider that is initially stationary. This will make the smaller glider move and the large one will continue to move as well. 2.) Inelastic Collision: A stroboscopic photo will be used showing a glider crashing into another glider that is initially stationary. When they collide, the two gliders will stick together and move. Masses, distances and times will be measured to calculate the momentum of the systems before and after the collision.
