Film a toss in slow motion against a door edge and step through the frames one at a time. Along the floor the ball covers the same distance every frame, right through the top; up the edge the steps shrink to nothing and reverse. Only vᵧ ever reaches zero, so the ball is never actually at rest — except at 90°.
