Brooke Cranford 2/25/21 PHYS 2108 Section 13 Keristen Wilkerson, Parth Mistry, Ryley Thompson Lab 6 – Conservation of Linear Momentum Purpose: The purpose of this lab is to look at the difference between inelastic and elastic collisions, conservation of linear momentum, and how any collision can conserve momentum as long as no external forces are acting on the object. Internal forces send the objects the other way after collision. elastic= conserve momentum and kinetic energy. Very similar to billiard balls act. Introduction: In the lab, we used dynamics tracks, steel carts, and the inclinometer to conduct the experiment. Data was given to us and we calculated momentum, kinetic energy, and percent change. Procedure: Level the track using the digital inclinometer and place two photogates near the center of the track. These will record the speed as the carts pass. For elastic collisions, arrange the carts so that the projectile is before Photogate 1 and target is between the two photogates, record data in table 1. Repeat the experiment twice, once with steel weight added to the target cart and once with the steel weight added to the projectile cart. For inelastic collisions, flip the target cart and repeat the experiment. For explosions, flip the projectile cart. For wrap-up, remove the target cart and only send the projectile cart down the track.
