Mairéad Kelly 10G Aim: To investigate the factors that affect the stopping distance of a catapulted margarine tub. In this experiment, I will be concentrating on the effect that varying the mass of the catapulted tub has on its stopping distance (sd.). Introduction: Things that move eventually have to stop. However, where they stop depends on several factors- their mass (the mass of the moving object), the speed the moving object is going at, the friction between the surfaces and the air (or water) resistance and movement around the object. The stopping distance (or sd.) of an object is how far it travels before stopping. As an object moves forwards, it has kinetic energy (KE) pushing it. However, as it moves, it also creates friction. This changes the KE (kinetic energy) of the moving object into heat energy. This means that there is less KE and more friction. The...
