Physics 8/27/09

Today in class we continued with our discussions of calculating velocity using graphs. We also did a lab using a sonar device that could measure where we were in relation to it. We then used it to calculate our velocity by walking from it and back towards it from distances of 2.5 meters and 1 meter. We moved at an almost uniform speed which meant that the slopes on our graphs were also uniform and were almost straight lines.
