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 = 2π (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/s²) 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 The data in the following table relates to measurements made of the period of oscillation T of a simple pendulum of variable length L.
