Newton Ball Posts

A stationary metal post shaped to resemble a pinball, mounted in the playfield as part of a Captive Ball assembly. Unlike a Newton Balls, which is an actual ball that transfers momentum, the Newton ball post is a fixed simulacrum — it cannot move or transfer energy. It serves as a structural element in the captive ball mechanism, providing a physical stop or reference point within the assembly. The distinction is subtle but mechanically significant: a true Newton ball participates in the physics of the shot, while a Newton ball post is simply part of the fixture.
