Provide a source of uniform velocity at an affordable price! Engage students in dimensional analysis with a 2-speed, battery-operated car. On a flat surface, the car travels at a constant velocity in a straight line long enough to conduct most standard time-and-distance experiments. Car body measures 4 x 7 x 3". For a corresponding classroom activity, see Carolina Essentials™: A Model for Constant Velocity on the Resources tab.

This item has been discontinued.

For the price, you can afford to buy every lab group its own car. On a flat surface, the car travels at a constant velocity in a straight line long enough to conduct most standard time-and-distance experiments. Great resource for teaching constant velocity and kinematics.

Car body measures 4 x 7 x 3". Some general classroom items are needed but not supplied. Also requires 2 C or 2 AA batteries (not included). Changing the car's battery configuration changes its speed:

  • High speed: 2 C or 2 AA batteries
  • Low speed: 1 C or 1 AA battery (in combination with the included battery jumper)

For a corresponding classroom activity that provides analysis and discussion questions, see Carolina Essentials™: A Model for Constant Velocity on the Resources tab.

Rated 1 out of 5 by from not constant velocity Each car had a different speed, which wasn't such a big deal. But a number of them were out of alignment and drove in a curve, which obviously is hard to use for a constant velocity experiment!

Rated 4 out of 5 by from This product provides two constant velocities for comparison of slope. A toy car, with two constant velocities, was needed for comparison of slope, in a professional development activity with grade 5 teachers. Teachers were able to use two C batteries (fast), or one C battery and the jumper (slow), to collect data in small groups. Teachers reported that the activity would be used with their grade 5 students. The feature that I did not like was the detachable tire. A few of the tires did not fit snugly on the wheels. Of 36 cars purchased, I noted 2 cars with a defective tire, each. Number 10 elastic bands were used to hold the tire to the wheel. A product, such as this, cannot be found in retail stores, anymore.
