College Physics I Laboratory PHSX 206N Angular Momentum Purpose To investigate conservation of angular momentum by directly measuring the moment of inertia and angular velocities for initial and nal positions of a system. Once students are done organizing their lab notes, I project a Conservation of Momentum Visual Guide on the interactive whiteboard. Physics 110 Lab will meet on Thursday, October 3, 2019. In this lab, a “shooter” nickel makes a non-head-on collision with a stationary “target” nickel. Preliminary information In LAB 09 we continue our study of conservation laws by analyzing experimentally a physical situation requiring the application “Conservation of Energy and Momentum”.
