The Foundation Physics Constant Motion Cart enables the investigation of the concept of constant velocity and acceleration.  When in motion, the Constant Motion Cart acts like a Ticker Timer.

As the car rolls over a strip of tape (not included), it pushes a marker down in regularly timed intervals, which creates a pattern of dots that vary based on the speed of the car. If the car is freely rolling down an incline, the dots will gradually have a larger distance between them, illustrating the idea of acceleration.

If you switch the motor to one of the four present speeds, students are given a stunning demonstration of constant velocity because no matter what constant speed the dots were traveling at, they are always equally spaced. You can also switch the car's wheels to roll freely.
