Lab Course 103A -Section 006 Physics Laboratory Report Lab number and Title: Lab B1: Simple Harmonic Motion Name: Nicholas Ramirez Group members: Carlos Skerrett, Gerome Garses, Shail Sheth, Conor Mccan, Erin Heidleberger Experiment Date : 3-3- 17 Instructor’s name: Sizhan Liu 1. OBJECTIVESThe objective of this lab was to determine the spring constant, k, by stretching the spring and applying Hooke’s Law. We also needed to verify theperiod of vibration of a body on a single spring independent of the amplitude. With measuring the period, T, of a pendulum length, L. Can be given by equation: T = √(mk) and T = 2√(Lg).2. THEORETICAL BACKGROUNDWhen a body of mass m, is suspended on a coil spring with constant k, and if the spring is stretched or compressed from its equilibrium position through a displacement d, the spring exertson the body a force that is proportional to the displacement and given by Hooke’s law:1. F = -ksF is the restoring force. The negative sign indicates the force direction is opposite to the directionof the displacement. If the spring is hung vertically, when the body is stationary, according to Newton’s First Law:2. F = mgCombined:

3: mg = ks We will determine the constant, k. When the body is stationary, we call the position of the system the equilibrium position of the system. If the body mass m, is now displaced from the equilibrium position of the system a distance x, there will be a net force acting on the body.
