We have redesigned our carts to provide added durability, versatility, and instructional value.
- Four mass trays make it easy to vary the total cart mass.
- Super-elastic trigger button allows for new types of collisions.
- An anti-roll peg ensures that the cart rolls on the track but not off the table.
- Top tray allows for easy attachment of sensors and masses.
- Two cart colors (teal and grey) make it easier to discuss collisions.
With the Dynamics Cart and Track System with Motion Encoder students can explore kinematics, dynamics, momentum, and energy with the added benefit of easy and precise optical motion sensing. The Dynamics Cart and Track System with Motion Encoder uses the same high-quality carts and track of the Dynamics Cart and Track System but includes a Motion Encoder Receiver and a cart equipped with optical motion encoding. The track also includes the necessary 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 to study momentum and energy are very easy to configure.
If you have ever been frustrated by the need to tweak the alignment of a Motion Detector, you will be pleased by the data your students collect using the Motion Encoder.
