McGee 2 Abstract : The purpose of this lab was to use the equations that describe the period of a simple pendulum to determine the local acceleration due to gravity. From our slope of T 2 vs. l (in meters), we were supposed to receive a y-intercept of .248. We received a slope of .2465. This leaves a percent error of .6%. Introduction : A simple pendulum is a mass suspended to a length of string. When the pendulum is started to oscillate, the period T can be found by the equation: T=2 π (l/g) 1/2 The variables that affect the period are the length of the string l and gravity, g. By rearranging the equation, we can yield a y=mx+b equation: l= (g/4 π 2 )T 2 . Equipment : String on a fixed position, stopwatch and mass on string. Experimental Procedure : To start this lab, we measured the diameter of the mass with verneir calipers. We then measured a certain length of the string, l. We started the
