Drop an item that bounces a few times and then really comes to rest

A dropped coin or ball that bounces by flipping its speed each frame either jitters on the floor forever or sinks into it, and its timing depends on the frame rate. Here is how to know the exact moment of every bounce and when to stop.

Why this works

Each bounce keeps only part of the speed, so every hop is lower and shorter and the sum of all the hops is a fixed time. Stopping once a bounce is too small to see gives a clean ending where a simulation would creep and jitter.

When not to use it

Not when the item can be pushed, rolls away or lands on something moving or tilted. A fixed schedule knows only a straight drop to flat ground, so there let real physics decide each bounce.
