Y10 Science - Level 5Road Safety

Big Idea: Speed, Road Conditions and Driver Behaviour (inattention, inexperience) contribute to vehicle crashes and their consequences.

Desired Learning OutcomesBy 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 ObjectivesUnits 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/areaWork done = Fxd

Should Know ObjectivesCalculate distance (under a v-t graph)Calculate acceleration.Acceleration due to gravity.F=ma.Kinetic energy = 1/2massv2 (conservation of)
