The data in the following table relates to measurements made of the period of oscillation T of a simple pendulum of variable length L. Theory predicts the following relationship: T = 2 (1) where g is the acceleration due to gravity. Table 1. Your instructor may give you a different set of data than this during the lab session. Length (L) cm 40.1 0.5 cm 34.8 30.3 24.8 20.2 14.9 10.1 Period (7) sec 1.28 1.17 1.13 0.98 0.92 0.76 0.66 0.05 sec g (cm/s) 1. Copy Table 1 and calculate a value of g for each data point using equation (1). Find the average of g for all data points. Call this value gi. Observe the rules of significant figures when doing the calculation. 2. Look at the g values in Table 1 and make a rough estimate for the possible error in g (call it Agi) from the range or spread of the data, i.e. Agi= Imax min 3. Record your experimentally determined value of g as gi Agi
