PHY 122 University Physics ! Mechanics Lab - Lab 10 Rotational Motion Report- Arizona State UniversityPHY 122 Lab 10 Rotational Motion Objective The objective of the lab was to investigate how the moment of inertia of a rotating mass depends on the rotation axis of the object. Using the static and dynamic moments of inertia calculated, the team looked at the system from an energy standpoint. Experimental Data: Data Analysis: Part 1: I s= 1 12 (.4 kg )(.032+.042)=. kg∗m2 .04 m∗41.6 rad s 2 9....
