Moment of Inertia and Rotational Motion Garret Hebert PHY 2311 Tues 1:00 garret.hebert@hindscc.edu Abstract: During this lab we will study what rotational Inertia is and how different shapes of masses and different masses behave inertially when compared to each other. We will specifically study the differences of inertia between a disk and a ring. We will use increasing forces to induce angular acceleration of both a disk and a ring of a certain mass. We will then then measure the differences
