Graphs made using a computer-interfaced Motion Detector can be use to study motion. A Motion Detector measures the distance to the nearest object in front of it. The computer reports the measurement as position along a line, and can calculate velocity and acceleration values. To determine distances, a Motion Detector emits and receives pulses of ultrasound. In this experiment, you will use a computer-interfaced Motion Detector to produce graphs of your own motion.


In this experiment, you will

  • Use a Motion Detector to measure position, velocity, and acceleration.
  • Produce graphs of your motion.
  • Analyze and interpret motion graphs.
