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.

Introduction to harmonic motion

We test whether Acos(wt) can describe the motion of the mass on a spring by substituting into the differential equation F=-kx

Harmonic motion part 3 (no calculus)
