# Constant Velocity Car

Item # 751482

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.
