The Motion Encoder Cart is a dynamics cart that is compatible with the Dynamics Cart and Track System. It includes the IR transmitter unit in a ready-to-use cart. The cart must be used with the Motion Encoder Receiver, and the track must have the Motion Encoder Track Strip installed.

A top tray has inserts for attaching the Dual-Range Force Sensor, Low-g Accelerometer, and Wireless Dynamics Sensor System. Removable inserts allow rapid configuration of magnets or hook-and-pile tabs for collision study. Vernier carts are also compatible with other common carts and tracks. Includes the cart only. Requires two AAA batteries (not included).
