Purpose The purpose of this lab was to examine collisions that are elastic and totally inelastic, to verify that momentum is conserved in all collisions, to measure the loss of kinetic energy in a totally inelastic collision, and to verify that an impulse results in a corresponding change in momentum of a particle. Theory Conservation of momentum requires that m 1 v o = -m 1 v 1 + m 2 v 2 and conservation of kinetic energy requires that m 1 v o 2 = m 1 v 1 + m 2 v 2 2 where m is the mass measured in kilograms and v is the velocity measured in meters per second. The relative approach speed between the masses must be equal to the relative separation speed of the masses. v F = {m 1 / (m 1 + m 2 )} v o Procedure We began the experiment by starting the computer and opening up the physics lab in LoggerPro. We then placed our aluminum track on the table and the two carts on the track so that the magnets on each cart were facing one another. We then attached light choppers on each cart longitudinally so that the portion of the chopper with the 15 alternating dark and clear regions is facing up. We placed the ring stands that were
