Velocity versus Force
While using the same spinning mass and maintaining the same radius,
students find the corresponding velocities for different hanging
masses. A graph of Force versus Velocity should yield a square root
graph and a relationship of
where k

is a constant.
Sample Data:
The following data is for a spinning mass of 22 g (#6 stopper) and a
radius of 0.5 m.
