The Real Pendulum Tommy Nguyen Phy101L 11/28/07 Composite Discussion: The goal of this lab is to find and study the motion of a physical pendulum for which the angular displacement theta will approach 45 degrees, and which has a small but detectable damping associated with it. We will also observe the conservation of energy in the pendulum system. T = 1.3 s +/- 0.1 s T 0 = 1.337s +/- 0.0 s T Real = 1.347s +/- 0.0 s As you can see, the values of the periods are very similar in value and the values agree with each other. The model of the real pendulum seemed to be the best simulation from our data. This was unexpected because we figured that the theoretical simulation would come closest to a sinusoidal wave since it was the experiment we could control the most which would lead to little error. The function for the harmonic pendulum is given as 0.34*Cos(0.5 + 4.70t). The function for the damped harmonic motion is given as e -0.05t (0.34*Cos(0.5 + 4.7t). The difference in the functions lies with the addition of the e -0.05t
