Name: Jonathan Tam Class : 12A Physics Experiment Report - Planning (b), Data Analysis Investigate impulse and rebound height Planning (a): To investigate the relationship between impulse and rebounce height. Planning (b): In order to measure rebounce height, we first have to select an apparatus which has a considerable rebounce. This also means something which undergoes a highly elastic collision. Tennis ball seems to be a good object to use since it rebounces at a considerable and measurable height. Measuring the height is a problem. Since the tennis ball reaches its highest rebounce height and stays there for not more that a second, it is very difficult, if not impossible, to measure this height at this split second. From literature formula, we have the followings: s = ut + 1/2at2 where s= displacement, u = initial velocity, a = acceleration, t = time Since the initial velocity is zero from rest, u becomes zero which gives us: s = 1/2at2 where s= displacement, a = acceleration,...
