Physics 11 IB The Simple Pendulum Rajesh Swaminathan June 18, 2006 1 Aim To go over the effect of a easy pendulum and to derive a nurse for g, the quickening cod to gravity. 2 Planning 2.1 Hypothesis By using other methods to run across the acceleration pay up to(p) to gravity g, the value of g should be close to 9.8 m/s2. 2.2 Procedure 1. Measure, record and average a sightly takings of measurements of the period T for 6 to 8 diverse lengths. 2. verify the equation of the pendulum T = 2 q L g by instrument of the graph of T2 vs L and determine the value of g from the graph. 1 3 information Collection aloofness (m) menses (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 Data Analysis See Table 2 and disposed graph. monger = 3.826 1 = 3.826 m/s2  g = (2)2 3.826 = 10.3 m/s2 2 Length L(m) Period T( s) Average T T2 1.954 1.00 1.959 1.956 3.826 1.955 1.879 0.91 1.888 1.882 3.543 1.880 1.747 0.80 1.754 1.755 3.081 1.765 1.759 0.82 1.757 1.759 3.094 1.761 1.653 0.72 1.645 1.646 2.710 1.641 1.501 0.

Because the length of a pendulum L, and the squ are of the period of the pendulum T2 are straightaway proportional, we were able to determine g by calculating the present of the T2 vs L graph. From our calcula tions, this value turned out to be 10.3m/s2,! plot the accepted value for the acceleration is 9.8m/s2. Percentage Difference = 10.3?9.8 9.8 = 5.10 % in that location are a few reasons for the small error in our estimation: 1. There was some uncertainty in commence the length of the pendulum L. 3If you want to get a full essay, bushel it on our website: OrderCustomPaper.com
