REFLECTION 2. We assumed that the tension providing the rotating torque was equal to the weight of the hanging mass; however, if that was true and T = mg… then in a free body diagram mg – T = 0, there would be NO acceleration, and the hanging mass COULD NOT fall. Conduct the following simple experiment. Set the masses to position 7, wind up the spin-mill, and measure the height from the floor to the bottom of the hanger pan. Use a stopwatch to time how long the hanger pan takes to fall. Use your data to find its falling acceleration, then use mg – T = ma to find the
