Y10 Science - Level 5 Road Safety Big Idea: Speed, Road Conditions and Driver Behaviour (inattention, inexperience) contribute to vehicle crashes and their consequences. • Desired Learning Outcomes • By the end of this topic you should: • Recognise the Units of speed, distance and time. • Be able to calculate and rearrange formulae for speed, pressure, force, kinetic energy and work. • Construct line graphs. • Understand the difference between mass and weight. • Understand the role of balanced and Unbalanced forces in road accidents. • Understand how speed and driver error contributes to injury and death on our roads
Must Know Objectives Units of speed, distance and time. Calculate average speed of a journey. Construct a distance time graph and a v-t graph. Difference between mass and weight. Balanced and Unbalanced forces. Pressure = Force/area Work done = Fxd Should Know Objectives Calculate distance (under a v-t graph) Calculate acceleration. Acceleration due to gravity. F=ma. Kinetic energy = 1/2massv2 (conservation of)
