What happens to people in automobile collisions is important information for car manufacturers. Crash dummies are often used in collision studies. Velocity is one of the most important factors in such collision studies. In this experiment, you will study the relationship between car velocity and the distance a “crash dummy” is thrown during a collision. A Motion Detector will be used to measure car velocity. You will use a ruler to measure the distance a crash dummy is thrown.


In this experiment, you will

  • Measure velocity.
  • Measure distances an action figure is thrown.
  • Calculate averages.
  • Graph the results.
  • Make conclusions from your results.
