1) Did your data display the expected relationship between the centripetal force and angular speed of the rotation? What evidence do you have of this? What changed when you changed either the mass or radius? 2) With the radius held constant, should a greater increase in force be required to increase the angular speed of a larger or smaller mass by the same amount? What did you observe experimentally in Part A?
