Whether we realize it or not, all velocity/speed measurements are made relative to some other object. When your car's speedometer reads 55 mph, the assumption is that the change in position of the car compared to the stationary ground is 55 miles every hour. However, not all velocity/speed measurements are made relative to a stationary object. The Constant Velocity cars allow students to experimentally investigate relative speeds as the cars with different speeds move in the same and in opposite directions.

Science students: Start your engines! “When I pull out the constant velocity cars, I usually hear a chorus of, ‘All right!’ from the class. That's what I think, too, because these powerful miniature dune buggies are so effective at helping my students really grasp what constant motion is and how to graph it.
