Rotational Inertia
PHY 200 & 230
Energy conservation principles are used to calculate rotational moments of inertia. For this apparatus, the linear relationship between inertia and the square of the distance to the axis allows a least squares fit to determine the mass used as well as the inertia of the empty apparatus. Graphs may be hand drawn or produced on computers.

Notes
Put out the CENCO Centripetal Force Apparatus found on S11,17,23. Make sure that each string is roughly 1.5 meters or long enough so that the weight hanger hits the ground. There is a bag with the label
Make sure that the room has plenty of graph and regular paper.
