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.
