It’s Race Day

Experiment #37 from Physical Science with Vernier


Air resistance, mass and friction are some factors that influence the speed of a soapbox racer. The same factors influence the speed of a lab car going down a ramp. In this contest, you will use principles you have learned in science as you race a car down a ramp. The fastest car will be the one that reaches the highest maximum velocity going down the ramp. Velocity will be measured with a computer-interfaced Motion Detector.


In this contest, you will

  • Apply motion concepts.
  • Measure velocity.
  • Have a little fun.
