Graphing Your Motion

Experiment #12 from Exploring Physical Science

Education Level
Middle School


Graphs made using a Motion Detector can be used to study motion. A Motion Detector measures the distance to the nearest object in front of it by emitting and receiving pulses of ultrasound. In this experiment, you will use a Motion Detector to produce graphs of your own motion.


  • Use a Motion Detector to measure position and velocity.
  • Analyze and interpret graphs of your motion.
  • Match position vs. time and velocity vs. time graphs.
