  • Essay / Conservation of momentum - 404

    Conservation of momentumObjective: 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 l Momentum is conserved in a closed system, the total momentum of the system before the collision must be equal to the total momentum of the system after the collision. Strobe photos will be used in calculations that will prove that momentum is conserved. 1.) Elastic Collision: A strobe photo will be used to show a large glider crashing into a smaller glider that is initially at rest. This will cause the small glider to move and the large glider to continue moving as well.2.) Inelastic Collision: A strobe photo will be used to show a glider crashing into another glider initially at rest. When they collide, the two gliders will stay together and move. - Masses, distances and times will be measured in order to calculate the moments of the systems before and after the collision. Data: V = d/t P = mx v1. ) Elastic collision: When Mass Distance Time Speed ​​Momentum Glider A before the collision 0.31 215 kg 0.009 m 0.6 s 0.015 m/s 0.00468 Kg m/s Glider B before the collision 0.15 580 kg — — 0 m/s 0 Kg m/s Glider A after Collision 0.31215 kg 0.005m 1.0s 0.005 m/s 0.00156 Kg m/sGlider B after collision 0.15580 kg 0.011m 0.6s 0.018 m/s 0 .00280 Kg m/s2.)
