Factors Affecting Circular Motion
Lab: Factors Affecting Circular MotionPurpose: See in page Hypothesis: See in pageProcedure: The rubber stopper was secured to a ropeThe rope was fed through the glass tubeThe length of rope was measured to 20cmThe alligator clip was clipped 2cm below glass tube as indicatorA steel washer was secured to bottom of ropeThe rubber stopper was swung and maintained a radius of 20cmThe time for rubber stopper to achieve 10 cycles was recordedSteps 6 to 7 were repeated two times for two extra trials2 steel washers were added to the bottom of the ropeSteps 6 to 9 were repeated three more timesThe time for 10 cycles was averaged outObservations: Number of WashersMass(kg)± 0.0003Time for 10 rotations (s) ± 0.2Frequency( Hz )Force FT (N)√Force√F (√N)Trial 1Trial 2Trial 3Average10.007138.18.08.18.01.250.070.2630.021706.06.26.16.11.640.210.4650.036605.65.95.75.711.750.360.6070.051004.24.34.64.32.320.500.7190.066003.94.14.14.02.500.650.81Sample Calculations:Force = mg        For 1 Washer, (0.00713 kg  x 9.8 m/s2) = 0.07Frequency = , where t is time for 10 rotations[pic 1]
