The ==Key Stage 4=====Meaning==='''Stopping distance''' is the distance a car vehicle travels between the driver noticing a hazard and coming to a stop. ===About Stopping Distance==='''Stopping distance''' is made of two parts:*[[Thinking Distance]] - The distance travelled by the vehicle between noticing a hazard and putting the foot on the brakes.*[[Braking Distance]] - The distance travelled once the vehicle has applied the brakes. '''Stopping Distance''' = [[Thinking Distance]] + [[Braking Distance]] '''Stopping distance''' depends on:*The [[speed]] of the vehicle - The greater the [[speed]] the larger the '''stopping distance'''.*The [[Human Reaction Time|reaction time]] of the driver - The longer the [[Human Reaction Time|reaction time]] the longer the [[Thinking distance|thinking distance]] and therefore '''stopping distance'''.*The conditions of the road and tyres - The less [[friction]] between the road and tyres the longer the [[Braking Distance|braking distance]] and therefore '''stopping distance'''.
