Unformatted text preview: Lab 126: Conservation of Momentum and Impulse Theorem Mario DeLaPaz November 10, 2010 Kui Chen Phys 111A Objective : In this laboratory you will measure the glider velocities before and after collisions (both elastic and inelastic). In addition, you will directly measure the impulse of a collision between the glider and the force probe and compare it with the change in the momentum of the glider. Theoretical Background: 1. Linear momentum : p = mv 2. Impulse J : J = FT 3. Elastic Collision : KE = constant 4. Inelastic Collision : Collision is fully inelastic between any two elements if they stick ( move with the same velocity ) after collision. Equipment List : Computer with ULI interface, Air track unit with compressor, Photogate, Glider, glider reflector, glider rubber bumpers, glider flag, wax & needle glider set, Glider weight, Motion detector, Force probe, Tripod stand with right clamp, Weight for force probe calibration, Digital scale on the counter....
