GCSE Physics coursework Problem The problem to be investigated is "how does the mass of a vehicle affect its stopping distance when brakes are applied?" This problem is related to the conservation of energy and will be investigated through a trolley going down a ramp. A simple trolley will be used to represent the vehicle and weights attached to the rear of the trolley via a pulley system will act as the brakes. Throughout the experiment energy will be transferred into many forms but no energy will be lost or gained. As the trolley is raised it gains potential energy, when released down the ramp this energy is converted to kinetic energy. When the trolley hits the horizontal surface all the energy will be kinetic. As the trolley continues to roll the kinetic energy within it, raises the weights on the pulley system. The kinetic energy is therefore converted to potential energy...
