Every watch a slinky gyrate back and forth. This is harmonic motion (a special class of oscillatory motion). In this tutorial we'll see how we can model and deal with this type of phenomena.
Intuition behind the motion of a mass on a spring (some calculus near the end).
We test whether Acos(wt) can describe the motion of the mass on a spring by substituting into the differential equation F=-kx
Figuring out the period, frequency, and amplitude of the harmonic motion of a mass attached to a spring.
