Describe thinking distance as: • the distance travelled between the need for braking occurring and the brakes starting to act. Describe braking distance as: • the distance taken to stop once the brakes have been applied. Describe stopping distance as: • thinking distance + braking distance. Calculate stopping distance given values for thinking distance and braking distance. Explain why thinking, braking and stopping distances are significant for road safety. Explain how certain factors may increase thinking distance: • driver tiredness • influence of alcohol or other drugs • greater speed • distractions or lack of concentration. Explain how certain factors may increase braking distance: • road conditions • car conditions • greater speed. Interpret data about thinking distances and braking distances. Explain the implications of stopping distances in road safety: • driving too close to the car in front (i.e. inside thinking distance) • speed limits • road conditions. Explain qualitatively everyday situations where braking distance is changed including: • friction • mass • speed • braking force. Draw and interpret the shapes of graphs for thinking and braking distance against speed. Explain the effects of increased on: • thinking distance – increases linearly • braking distance – increases as a squared relationship e.g. if speed doubles braking distance increases by a factor of four, if speed trebles braking distance increases by a factor of nine.
