Part 1 Part 1a t 19.0 sec t 20.3 sec Average t 19.7 sec % difference measured vs calculated 1.5 Part 1b t 19.9 sec t 20.1 sec Average t 19.7 sec % difference measured vs calculated 0% Does the amplitude affect the period? No. T=2π√L/g Part 2 t 25.0 sec T 26.8 sec Average t 25.9 sec Measured T with L=100 cm Measured T with L=180 cm 2.0 sec 2.6 sec In an ellipse t 26.7 sec t 27.4 sec Average t 27.0 sec How do your measurements compare with theory? It proves it. Because T=2π√L/g, the period is affected by the length of the pendulum

Unformatted text preview: Part 3 T 19.8 sec T 19.9 sec Average t 19.85 sec Measured T with mass 1 Measured T with mass 2 2 sec 1.95 sec How do your measurements compare with theory? Again, T=2π√L/g, the hanging mass is not a factor in the period of a pendulum. Calculated period based on L=100 cm T=2 sec. Calculated time for N oscillations N t=NT 10 20 sec....
