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". Requires 2 C or 2 AA batteries (not included). Instruction manual includes sample labs and suggested extensions for advanced students.

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 for teaching velocity, centripetal acceleration, and angular velocity. Combine with other lab equipment to also teach the coefficient of sliding friction. Comes with an instruction manual that includes sample labs and the following lab extension suggestions for advanced students:

  • Calculation of centripetal acceleration and angular velocity
  • Finding the coefficient of sliding friction with a rigid board
  • Finding the coefficient of sliding friction with a spring scale
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 jumper)
Car body measures 4 x 7 x 3".

  • WARNING: CHOKING HAZARD - Small Parts. Not for children under 3 yrs.

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.
