1) Give two reasons BESIDES systematic measurement ("human") errors that could explain any discrepancies between your average experimental value and the calculated value of moment of inertia. 2) The string should be level with the table top as it stretches from the drum of the rotation table to the pulley. Why is this important? 3) If you hung three times the mass off the side of the table, would you expect different results for the moment of inertia? If so, why? If not, what would be different?
