Just finished an experiment that seems totally screwed up. We let a roller decend an inclined plane of 7 and 9 degrees respecitvely and let it roll from 25 to 50 cm in increments of 5 cm. We then graphed distance v. time and distance v t^2. I thought the first should be a log scale, the second a straight line, but I couldn't get a good fit. What should these graphs tell me about the motion of the roller? How do I compute the acceleration due to gravity from the GRAPHS?(adsbygoogle = window.adsbygoogle || []).push({});
