For Part 1, which of your two graphs verifies that Fc = mv^2/r? Is this relationship a linear relationship? Compare the equation for a line through the origin, y = mx, to the equation Fc = mv^2/r, and explain what the slope of the graph of Fc vs. v^2 represents. Remember that the m in the equation for a line represents the slope, and the m in the centripetal force equation represents the mass of the stopper.
