Physics 2048 Lab Report Lab 10: Harmonic Motion (Part I) Date Due: November 18, 2010 Abstract: The purpose of this experiment was to first determine the spring constant, k , of the spring, which is measured by applying Hooke’s Law. In order to verify Hooke’s Law, we used a mass of .030 kilograms to add force to the spring, and by measuring the spring displacement while applying those forces, we could determine the value of k . The basic equation that we used to determine the spring constant was kx= mg, where k is the

spring constant, x is its displacement due to the mass, m is the mass applied and g is the acceleration of the force of gravity. We also were able to calculate the spring constant a second way by using the equation ϖ =( k/ m). The latter part of the experiment was to determine the effect that mass had on the spring. One value was calculated from using the spring constant and the other value was measured by using the times that was found for the spring to do 60 oscillations. The period of the motion in seconds can be expressed as T= (2π( m/k). Some results of this experiment were that T increased as mass increased. Masses 0.010, 0.020 and 0.030 had T’s of .2742, .3873, .4750 seconds respectively which helped us to conclude that all the data collected in the experiment, obeyed Hooke’s Law. Introduction:
