motion detector blog

today we learned about motion detectors and graphing motion. I learned that when you speed up towards the motion detector the graph line goes down and if you move backwards it goes up. It is really hard to move and go backwards without making the graph line go crazy, you have to move really smoothly and at the same rate, and that is almost imposible. When you run faster towards or away from the detector the velocity for time is kind of like mile per hour, the faster you go, the more the graph line moves up. when you are slow the line goes slowely up, going up slower per second then when you move faster.
