Lab B1: Simple Harmonic Motion Name: Tomasz Dulian Experiment Date: 3/6/19 Submission Date: 3/13/19 PHYS 103A Professor Huang Group: Dipen, Hrushi, Tomasz, Leandro, Diego, Matthew 1. Introduction 1.1) Objective To determine the spring constant k by stretching the spring and applying Hooke’s Law. To verify that the period vibration of a body on a spring is independent of the amplitude, and is given by:(1)T=2π√❑. To measure the period T of a simple pendulum as a function of the length L of the pendulum, and verify that it is given by(2)T=2π√❑ 1.2) Theoretical Background 2. Experimental Procedure 3. Results 3.1) Experimental Data
