EXPERIMENT 12. ANGULAR MOMENTUM 11. Was the change in total angular momentum significant compared to the uncertainty? Based on this can you conclude that angular momentum was conserved? 12. create a column for the total rotational kinetic energy KE Rot = 1 2 I 1 ω 2 1 + 1 2 I 2 ω 2 2 . Plot this versus time on a separate graph. 13. Friction between the disks caused them to change their angular velocity until they were moving at a common angular velocity. Since there is friction, one would not expect mechanical energy to be conserved. What percentage of the kinetic energy was lost in

Unformatted text preview: the collision? Report In addition to the standard elements of a well written lab report described in the introduction to this manual, your report must include: 1. Your momentum graph and energy graph for each data run 2. A conclusion in which you address the following: (a) Whether or not angular momentum was conserved. (b) Whether or not the energy of the system was conserved. 78...
