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 is for a hanging mass of 500 g and a radius of
0.5 m.
