Newton Balls

A Captive Ball Targets in which a stationary pinball — fixed in the playfield assembly — transfers the momentum of the ball-in-play to a movable captive ball behind it, following the same principle as a Newton’s cradle desktop toy. The Newton ball itself does not move; it sits fixed and relays kinetic energy from one ball to the next. The mechanism appeared on approximately 16 IPDB-cataloged machines and creates a distinctive feel: the player’s shot stops dead on contact while the captive ball on the far side springs to life and strikes the scoring switch.
