Kristin Favreau October 26 1999Purpose 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 conserved1 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 When MassDistance TimeVelocity MomentumGlider A Before Collision 31215 kg 009m 6s 015 ms 00468 Kg msGlider B Before Collision 15580 kg 0 ms 0 Kg msGlider A After Collision 31215 kg 005m 10s 005 ms 00156 Kg msGlider B After Collision 15580 kg 011m 6s 018 ms 00280 Kg msWhen MassDistance TimeVelocity MomentumGlider C Before Collision 3105 kg 016m 10s016 ms 004968 Kg msGlider DBefore Collision 3000 kg
