Tyre surface: If the tyre is new, it will have surface with depressions which will offer more friction compared to old tyre whose surface-depressions are worn out and it is more flat, so it offers less friction. Therefore, new tyre will have less stopping distance, as force of friction is more. Thinking distance is affected neither by friction between tyre and road, nor by friction between brake and tyre. If road has a wet surface, it has less friction so the vehicle will skid farther, and vice versa. The braking force, i.e, friction between tyre and brake is unaffected by road condition or tyre surface. Hence the distance the vehicle travels WHILE retarding due to "braking force", is not same as stopping distance, because even when the wheels are stopped rotating due to braking force, the car will skid a little distance- this total distance is the stopping distance.
The distance needed to stop also increases.

Stopping distance as in braking distance: Braking distance refers to the distance a vehicle will travel from the point where the brakes are fully applied to when it comes to a complete stop. It is affected by the original speed of the vehicle, the type of brake system in use, the reaction time of the driver/rider and the cefficient of friction between the tires and the road surface.
It just depends on how quickly it stops. In some crashes the vehicle may go on out of control for some distance, in head-on crashes it will stop very quickly
kinetic
The kinetic energy of the vehicle when it is travelling faster is four times as great. It the brakes apply the same retardation and the friction from the tires on the road surface is unchanged then the stopping time will be four times as long.
The distance your vehicle travels while stopping depends on various factors such as your speed, road conditions, and reaction time. On average, a car traveling at 60 mph can take anywhere from 100-130 feet to come to a complete stop.
Trains require a long stopping distance.
Stopping distance for a motor vehicle is a combination of two factors.First the reaction time of the driver.Then the braking distance of the vehicle once the driver has reacted and applied the brakes.The two equal the stopping distance.
stopping distance is the distance it takes for a vehicle to come to a full stop from the moment you apply the brakes
The more friction, the quicker the vehicle will stop, meaning less stopping distance.
No - the stopping distance depends on the speed of the vehicle - it' not simply a case of 'doubling-up'.

The greater the mass of the car and its occupants the longer the stopping distance that is required for the vehicle. Stopping distance is calculated by taking into account car mass and reaction time in braking
