==Key Stage 4==
===Meaning===
'''Braking distance''' is the distance a vehicle travels from the moment the brakes are applied to the moment the vehicle stops.
===About Stopping Distance===
'''Braking distance''' depends on:
*The [[speed]] of the vehicle - The greater the [[speed]] the larger the '''braking distance'''.
*The conditions of the road and tyres - The less [[friction]] between the road and tyres the longer the [[Braking Distance|braking distance]]. Water, oil or ice on the road all reduce the [[friction]] between the tyres and the road, causing the '''braking distance''' to be greater than for a dry road.
: Different road surfaces have different amounts of [[friction]]. The painted lines on the road and the metal of a manhole cover are both low [[friction]] surfaces which are especially dangerous for motorcycles which only have two wheels (at least with 4 wheels a car will have 3 of them on the normal road with 1 on the slippery surface of a line or manhole cover).
