Motion Detector Blog

Today in class we used a motion detector that recorded our motion but in many different ways. My partner was Louisa. We detected our motion by acceleration vs. time, velocity vs.time, and distance vs. time. In acceleration vs. time we learned that the detector lines move very quickly because its hard to stay still. We also learned that the faster you move and walk, the higher the lines went. Our second motion detector that we did was velocity vs. time. Well first of all, velocity means how much distance you are covering and the amount of speed there is. So, we noticed that when the motion detector was detecting us while we were moving, the slower we went the line stayed the same, but the faster we went the line went all over the place. The last one that experiment that we did was detecting the distance. We learned that if you walk slow for 3 seconds the line will go up a little, and you pause (stop) for 3 seconds the line just moves straight and doesn't go up or down for 3 seconds, and if you start walking again the line will go up. I've learned a lot about velocity, distance, and acceleration, and I think this project was a fun and educational. I thought the motion detectors were pretty cool. I don't have any questions.
