Angle Time for 10 oscillations Period T (s) 20 15 5 When you vary the angle through which the pendulum oscillates you are changing the amplitude of oscillation. Q1: Based on the data in table 1, does period depend on the amplitude of oscillation? Explain. 5. Now vary the length of the pendulum and measure the period like you did before. This time the angle of displacement will be 30 degrees for all trials. Table 2: Period measured by varying length Length Time for 10 oscillations Period T (s) (degrees) ti (s) t2 (s) t average ($) T = t average /10 0.70 0.60 0.50 0.40 I 0.35 Q 2: Does changing the length of the pendulum affect the period of oscillation? Explain. 6. Next vary the mass of the bob and find the period of oscillation. Keep the angle at 30 degrees and the length at 0.70m.
