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.

Soccer on the moon

After moving to the moon, I've discovered that playing soccer is much different. When i kick a soccer ball, it goes much further than it does on earth. Because the acceleration due to gravity is much less, when I kick a ball goes higher and and stays in the air longer. And because there would be very little inertia the ball would continue to move through space. When I kick the ball, i assume that I would be forced upward just slightly due to the force of my leg swinging. I don't think I would go to far because i am much more massive than the ball.
