Click on Stopwatch. Make sure that speed is set to Normal (radio button) and Friction (slider) is set to None. Throughout the experiment, do not increase the Amplitude beyond 30 degrees. Choose Earth in Gravity window for Parts 1, 2 and 3. Part 1 - Time Period vs. Mass - Length, Gravity 8: Amplitude constant 1. Choose constant values for length, gravity and amplitude. Choose mass of the pendulum to be 0.1 kg and measure time for 10 oscillations. 2. Keep length, gravity and amplitude same. Change mass to 0.4 kg and again measure time for 10 oscillations. Repeat this for a total of 6 readings. (Mass values in kg: 0.1, 0.4, 0.7, 1.0, 1.3, 1.5) Part 2 - Time Period vs. Amplitude - Length, Gravity 3: Mass constant 3. Choose constant values for length, gravity and mass. Choose amplitude of the pendulum to he 5 degrees and measure time for 10 oscillations. 4. Keep length, gravity and mass same. Change amplitude to 10 degrees and again measure time for 10 oscillations. Repeat this for a total of 6 readings. (Amplitude values in degrees: 5, 10, 15, 20, 25, 30)
