Physics Pendulum

Physics 11 IB The impartial Pendulum Rajesh Swaminathan June 18, 2006 1 Aim To investigate the action of a fair pendulum and to attain a appreciate for g, the intensify cod to gravity. 2 Planning 2.1 Hypothesis By using other methods to candidature across the acceleration refer qualified to gravity g, the comfort of g should be close to 9.8 m/s2. 2.2 Procedure 1. Measure, record and average a sightly number of measurements of the dot T for 6 to 8 diverse lengths. 2. Verify the comparability of the pendulum T = 2 q L g by instrument of the graph of T2 vs L and fall the value of g from the graph. 1 3 information Collection aloofness (m) flowing (s) 1.954 1.00 1.959 1.955 1.879 0.91 1.888 1.880 1.747 0.80 1.754 1.765 1.759 0.82 1.757 1.761 1.653 0.72 1.645 1.641 1.501 0.60 1.506 1.504 Table 1: data Collection 4 entropy Analysis See Table 2 and disposed graph.

60 1.506 1.504 2.261 1.504 Table 2: Data Analysis 5 Evaluation In this lab, we were able to estimate the value of the acceleration due to gravity g on Earth by means of a simple pendulum. Because the length of a pendulum L, and the squ are of the period of time of the pendulum T2 are directly proportional, we were able to determine g by cypher the position of the T2 vs L graph. From our calculations, this value turned out to be 10.3m/s2, fleck the accepted value for the acceleration is 9.8m/s2. Percentage discrepancy = 10.3?9.8 9.8 = 5.10 % there are a few reasons for the small fallacy in our estimation: 1. there was some uncertainty in beat the length of the pendulum L. 3If you regard to get a all-embracing essay, set it on our website: Orderessay
