The Motion Encoder Cart is a dynamics cart compatible with the Vernier Dynamics Cart and Track System. The Motion Encoder Cart replaces a motion detector when used for dynamics cart-on-track activities. 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.
The cart must be used with the Motion Encoder Receiver, and the track must have the Motion Encoder Track Strip installed.
