Velocity versus Mass
While maintaining the same hanging mass and radius, students find the corresponding velocity for different
spinning masses. A graph of Velocity versus M
s
should yield a graph with the relationship of

is a constant.
Sample Data:
The following data are for a hanging mass of 500 g and a radius of
0.5 m.
