Distance vs. Time Graphs

                

               How would you detect motion? Well in class we used motion detectors to try to match a graph on the monitor. What we did was that we connected the motion detector to a lap top, second we had someone stand in front of the monitor and they had to walk backwards and towards the detector. As the person was walking the detector was making a graph on the lap top. So when we had the graph we made we then had to match our graph with a graph that the detector already had. After we did the walking we had to record it on a lab we had in our notebooks and explain what movements we had to do so we could make the shape.

                I think these graphs are important in science because with these graphs you can tell if you are moving or not. So it is a good way to detect motion or to show motion. This is a good way to show motion to someone who isn't in the experiment with you.
