Lab B1: Simple Harmonic MotionProfessor:Haizheng ZhuangPhysics103A-005Experiment Date: 10/16/2018Due Date:10/23/2018Introduction:The objective of the simple harmonic motion lab is to determine the spring constant kof aspring by adding various weights and measuring the new length. The other objectives are to determine the period of oscillation of a spring and similarly the period of oscillation of a pendulum. The equations used for this lab were 1.T=2πmk2.T=2 πLg3.F = k * s Experimental Procedure:Follow procedure listed in Physics 103A Lab Manual, 7th Edition, on pages 32-33.Results:Table IMass of total weight m(kg)Weight of total mass w (N) = mgPositiony1Displacementy = y1 – y0(m)0.05+0.202.45 N0.295 m0.013 m0.05+0.303.43 N0.321 m0.039 m0.05+0.404.41 N0.345 m0.063 m
