Freefall Adapter
This adapter is an auto release mechanism that works with Photogate Timers, Smart Timer, and ScienceWorkshop Interfaces.
When the steel ball is dropped from the release mechanism, the computer automatically starts timing. When the ball hits the receptor pad, timing stops. Timer measurements of “g” are accurate and repeatable.
