  • Cars, the highway code and collisions
    • the total stopping distance of a vehicle = thinking distance + braking distance
    • factors which affect these distances
      • the total stopping distance of a vehicle = thinking distance + braking distance
      • velocity of the car
      • reaction time of the driver
      • mass of the driver
      • condition of the vehicle's brakes and tyres
      • condition of the road surface
      • weather conditions
    • in the UK, the speed limit on a motorway for cars 70mph but when they have extra mass (e.g. caravan) it is 60mph
      • in built-up/ heavily built up areas it is 20/30mph
    • traffic cameras are connected to computers to calculate the velocity of passing vehicles to see if they are within the speed limit
    • Safety features in cars reduce the numbers of injuries/ deaths when cars are involved in accidents.
      • safety belts
      • air bags
      • crumple zones
      • safety cages
      • all these features act by increasing the time taken for the collision to take place
        • -reducing the momentum of the car passengers and the force acting on them
