Simple Harmonic Motion
A restoring force always points toward the equilibrium position. Pendulum Mass on a spring SHM: restoring force is proportional to displacement
2
For a spring: F=-kx PE= k= spring constant
amplitude: max displacement from equilibrium period: time for one cycle frequency: cycles per unit of time

Mass on spring: pendulum:

A spring with constant 245N/m has a mass of 0
A spring with constant 245N/m has a mass of 0.676kg attached to it and is sliding on a frictionless table. If its furthest distance from equilibrium is 12.0cm, what is its maximum speed? A=.120m, k=245N/m,m=0.676kg,vmax=? PEmax=.5(245)(.122) = E E = KEmax = .5mv2
