Coefficient of Restitution Rosalie Laconto Anna Bagley, Kara O’Neil Conceptual Physics G December 1, 2015 Abstract: Did you know that when you drop a rubber bouncy ball, you are witnessing phy... sics in action? In this experiment, multiple trials were conducted and showed that when you drop a rubber ball one meter above a tabletop surface, it will bounce back to a point slightly less than the starting point. This is due to the conservation of energy and the fact that a perfect elastic collision is not possible. A total of 10 trials were conducted with the same rubber ball dropping 1 meter above a tabletop surface. With the help of a slow motion camera, we were able to determine the exact bounceback height of the ball. The results were ranging from 8597 cm (0.85m – 0.97m). It was found that the coefficient of restitution of the ball, or the ratio of the objects speed after impact to the speed before impact, was 0.95 J. We found this using multiple equations learned in class. This experiment was very simple and intriguing, so keep reading to find out more information! [Show More]
