Motion Detector Lab

Today we used motion detectors to detect our motion and figure out how acceleration and velocity and distance are related.
  • The lines lines were very wiggly and all over the place, I assume this is because it is very hard to stand completely still.
  • I think it is possible to have zero acceleration and positive velocity, because if you can keep a constant speed with out changing speed at all there is no acceleration.
  • If you move towards the motion detectors the distance is negative therefor providing a negative slope. If you walk away from the detectors the distance is positive providing a positive slope.
One thing thing that struck me was that if you stay still the line stays straight, at first that didn't make sense but know I see how it relates to the axis.
