When does an object
un- dergo simple If the restoring force is proportional to the displacement
harmonic motion
(SHM)?
1. amplitude the maximum displacement from equilibrium
2. period (T) the time required to complete one cycle (back and forth)
3. frequency number of cycles per second
4. relation for frequency f = 1/T
and period
5. Equation for the T = 2π (m/k)
period of oscillation for
a mass (m) on the end
of an ideal massless
spring
6. sinusoidal a way to describe simple harmonic motion where the
displacement as a function of time follows a sine or cosine
curve
7. General solution for 8. equation for angular ve- locity (w)
dis- placement as a
function of time for
simple harmonic
motion
