When the radius is increased, does the period of rotation increase or decrease? Explain your conclusion using both the collected data and the theory. 2. When the radius and the mass of the rotating object are held constant, does increasing the period increase or decrease the centripetal force? Justify your answer. 3. If, while the rotation speed is kept constant, the reference mass m is increased, will the centripetal force increase or decrease? Explain your reasoning. 4. Can you think of one possible cause of the percent difference found in Part I? Explain your reasoning. 5. Can you think of one possible cause (different from the previous one) of the percent difference found in Part II? Explain your reasoning. 82
