Practice question The period of a simple pendulum is measured by timing 50 oscillations. For lengths of 1.000 m, 0.750 m, and 0.500 m the total times are 99.8 s, 86.6 s, and 71.1 s. Determine the period of motion and the mean value of g for each measurement and compare it with the accepted value. Plot T ² versus L and obtain a value of g from the slope of the graph.
