The rules that govern the mechanics of a slinky are Hooke's law and the effects of gravitation. Due to simple harmonic motion the period of oscillation of a dangling Slinky is where T is the time of the period of oscillation, m is the Slinky's mass, and k is its spring constant. In the state of equilibrium of a slinky, all net force is cancelled throughout the entire slinky. This results in a stationary slinky with zero velocity. As the positions of each part of the slinky is gove…
