Tim Matthews Everett Rauch April 16, 2008 Physics 133 Lab #4 Yipeng Yang Abstract In this experiment we began to discuss the theory of simple harmonic motion. In this experiment we measured the harmonic periods of springs and a pendulum. The goal of this experiment was to obtain values for length of the pendulum and time it took for one period (full swing from left to right) and compare it to the accepted value. Our obtained value was 4 which was .065% off from the accepted value of 4.028. For the spring part of the experiment we obtained the same value, which leads me to believe that simple harmonic motion for a pendulum with less than 15 degrees of release is equal to that of a spring. Theory Simple Harmonic Motion (SHM) is the motion of a simple harmonic oscillator, a motion that is neither driven nor dampened. The motion is periodic, which means it repeats itself as long as no outside forces act upon it, such as friction or air resistance. Using the equation Av c T Mr F 2 / 4 = you can get the Force. Since we already have the mass, radius and the time it took. Procedure Part A: Pendulum Part 1. Take the weight of the mass, and attach it to the pendulum at a length of .
