Physics Pendulum

Physics 11 IB The Simple Pendulum Rajesh Swaminathan June 18, 2006 1 Aim To investigate the effect of a honest pendulum and to derive a evaluate for g, the quickening cod to gravity. 2 Planning 2.1 Hypothesis By using other methods to run across the acceleration call fitting 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 effect of measurements of the period T for 6 to 8 diverse lengths. 2. corroborate 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 continuance (m) sleek (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: information Collection 4 Data Analysis See Table 2 and disposed graph. side of meat = 3.826 1 = 3.826 m/s2  g = (2)2 3.826 = 10.3 m/s 2 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 0.60 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 the pendulum T2 are at once proportional, we were able to determine g by calculating the note of the T2 vs L graph. From our calculations, this value turned out to be 10.3m/s2, snatch 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 hum the length of the pendulum L. 3If you want to get a full essay, clique it on our website: OrderCustomPaper.com
