M9 Simple Harmonic Motion (PHY 158) this lab you will accomplish the following tasks: In this lab you will accomplish the following tasks: 1. Measure the spring constant k of a spring 2. Suspend a mass m from the end of the spring. Set the mass- spring system to oscillate and measure the period of oscillation T as function of mass m 3. Measure the damping of the oscillation in the spring-mass system et a pendulum of length to oscillate Measure the period of 4. Set a pendulum of length to oscillate. Measure the period of oscillation T as function of A A Oscillating (page 1) Tacoma Bridge

The force on the sping is equal to k SL m = A mg kS = Thus if you plot versus you will get a stright line that passes through mS k k g = the origin with slope () kg slope g =→ = × (page 2)
