Linear Momentum in Collisions Shahd Abdalla Goal: To investigate the Law of Conservation of Linear Momentum in collisions. Simulation Used: Collision Lab from the PhET at the University of Colorado . Preliminary Settings. Open the simulation Collision Lab . From the menu on the right, select: Show Values In the yellow window below, click on "More Data" Activity 1: Elastic Collisions in one dimension. Ball 2 is initially at rest. On the menu to the right, slide the indicator all the way to the right for a perfectly elastic collision. For the given masses and initial speeds of the two balls, determine the velocity and momentum after the collision. Ball Mass (kg) Before the Collision After the Collision V (m/s) Momentum (kg.m/s) v (m/s) Momentum (kg.m/s) 1 0.50 1.20 0.6 0.0 0.0 2 0.50 0.0 0.0 1.2 0.6 Momentum initial= 0.6 Momentum final= 0.6 Ball Mass (kg) Before the Collision After the Collision v (m/s) Momentum (kg.m/s) v (m/s) Momentum (kg.m/s) 1 1.50 0.90 1.35 0.45 0.675 2 0.50 0 0.0 1.35 0.675 Momentum initial= 1.35 Momentum final= 1.35 Ball Mass (kg) Before the Collision
