The Physics of a Falling Slinky
When a Slinky is dropped, the bottom of the Slinky remains motionless as the top collapses towards it, making it appear to the observer as though the Slinky is levitating. By considering the Slinky as a tightly wound, pretensioned spring, the static equilibrium of a hanging Slinky was solved for using Hooke's law (Equation 1).

THE FALLING SLINKY
the full extent of the slinky remains utterly at rest except for the top which falls due to gravity and gathers more and more of the slinky as it falls. The bottom of the slinky therefore remains motionless until the full
The Slinky Drop Experiment Analysed - Physics Forums
2024年3月28日 · What is The Slinky Drop Experiment? The slinky drop experiment is exactly what it sounds like: Support a slinky at one of its ends. Let the rest of it hang freely under gravity until it has reached equilibrium. Let go of the slinky! Observe how it falls under the influence of gravity and internal forces.
Recent interest has focussed on the behaviour of a slinky dropped from a hanging state. It is surprising that the bottom of the falling body remains stationary while the top collapses, coil upon coil, until it reaches the bottom. Several videos of this phenomenon are available on YouTube [3].
Let’s consider a one-dimensional model problem of a falling bar; the physics are very close to the Slinky problem, but a little simpler. 1 We’ll take the x-direction as down, with the top of the bar
approximates the dynamics of a real slinky and we give a careful mathematical explanation for this phenomenon. 1. Introduction. In this note, we study a simple dynamical system that is an approximation to a slinky that falls after being released from a vertically hanging position. We model the slinky as a chain of n+ 1 bodies each having mass m.

2012年8月22日 · We present a modification to an existing model for a falling tension spring (Calkin 1993) and apply it to data from filmed drops of two real slinkies. The modification of the model is the inclusion of a finite time for collapse of the turns of the slinky behind the collapse front propagating down the slinky during the fall.

2013年7月19日 · The center of mass acceleration will be the same at every point the slinky is falling until the bottom hits the ground, but the slinky is also pulling itself together as it is no longer under tension. Thus, the top of the slinky will be falling with a larger acceleration, and the bottom part of the slinky will be falling more slowly.
