Unformatted text preview: Alexander Hyatt Physics Lab 124-021 March 8, 2007 Abstract In this experiment, the concepts of centripetal acceleration and centripetal force were introduced. A rotating platform was used to apply these concepts of rotating bodies and verify several aspects of Newtons Second Law for rotational motion. The percent difference between the measured values and the experimental values were fairly high, because there were several types of errors with the experiment. The main error was that the platform needed to be rotated at a close to constant velocity, so that acceleration is zero, which was hard to do because the human hand has trouble turning the object at a constant velocity. Experiment Table 1 Table 1 contains the data collected for exercise 1. The centripetal mass was measured to be .209 kg and the hanging mass .056. The platform was rotated ten times and the time was taken for those ten rotations. Then that time was divided by 10 to give the amount of time per rotation. This was done seven times and then the results were used to find the Centripetal Force through Graph 1.
