On which factor, among other elements, does the braking distance of a vehicle depend?

Question

DentroTest · Accepted Answer

Braking distance is the distance the vehicle travels from the moment the driver applies the brake until it comes to a complete stop. It depends mainly on speed (it is proportional to the square of the speed: if the speed is doubled, it is multiplied by approximately four), on the condition of the roadway (wet, with loose gravel, etc.), on the mass of the vehicle and on the mechanical condition of the brakes, suspension and tires. Saying that it depends only on the driver's physical condition is incorrect, because that affects the reaction time and the reaction distance, not the braking distance proper. Claiming that it is a fixed figure is false, because it changes with speed and with the conditions of the vehicle and the surroundings.
