2 Abstract In this laboratory experiment is to better understand angular momentum. With the use of rotating apparatus, we are able to examine the motion of rotating bodies utilizing the principle of conservation of angular momentum. In order to do this lab we are going to have to use data from the previous lab, Inertia. Using the data from the previous lab we are able to determine angular momentum because it is equal the inertia multiplied it’s angular acceleration. In this lab we will be using many kinematic equations for linear rotational motion with constant acceleration, found on page 12-1 of the lab manual.
3 Data : Data Table 1: Exercise 1 Moment of Inertia of solid disk, I c Moment of Inertia of hollow cylinder, I D Initial moment of Inertia of the system, I i Final Moment of Inertia of system, I f For the values above, the I C and M D values are data found in the previous lab. As for the rest of the following values, refer to the calculations section to see how we determined each value. Initial Rotational Speed, w i (rad/s) Final Rotational Speed, w f (rad/s) 15.093 9.658 15.975 10.5 16.311 10.392 17.819 11.978 14.847 9.608 15.852 10.258 18.658 11.991 16.81 11.117 16.501 10.975 19.452 12.686 Slope of graph:
