With the Dynamics Cart and Track System with Motion Encoder, students can explore kinematics with the added benefit of easy and precise optical motion sensing. The Dynamics Cart and Track System with a Motion Encoder includes a Motion Encoder Receiver and a cart equipped with optical-motion encoding. The track also includes the Motion Encoder Strip. An optical sensor beneath the dynamics cart senses the passage of the cart over a marked strip on the track. The position information is sent as an encoded IR signal to a receiver at the track’s end. By avoiding the possibility of stray sound reflections, this optical-only system provides excellent, repeatable, and noise-resistant motion data.

Because the position information is relayed by a narrow IR beam, the addition of a second Motion Encoder Cart and Receiver allows students to record the positions of two carts simultaneously. Now collision experiments are easy to configure.
