Velocity versus Radius
While maintaining the same hanging mass and spinning mass, students find the corresponding velocity for
different radii. A graph of Velocity versus Radius should yield a graph with a relationship of
where k

is a constant.
Sample Data:
The following data is for a hanging mass of 500 g and a spinning mass of 56 g (#10 stopper).
