Braking distance refers to the distance a vehicle will travel from the point when its brakes are fully applied to when it comes to a complete stop.
When the speed of a vehicle doubles, the braking distance is increased by approximately four times. This is because the braking distance is directly proportional to the square of the speed.
On dry, level pavement, with decent tires? About 120 feet. Many things affect this calculation. With worn tires the distance can increase to 210 feet. Dirt roads require longer braking distances than pavement. Ice can increase the braking distance by hundreds of feet. Braking down a hill, depending upon the slope, can double the braking distance, whereas braking up hill can halve that distance. If you lock the tires, you typically increase the braking distance. You can reduce the distance by pumping the brakes. Anti-lock brakes allow the tires to slip, which decreases the braking distance. Extra weight in the vehicle increases the braking distance. Refer to the link below for calculating the braking distance at different speeds with different tire wear on dry, level pavement.
Braking distance
Braking in a moving vehicle is applying the brakes to slow or halt movement, usually by depressing a pedal. The braking distance is the distance between the time the brakes are applied and the time the vehicle comes to a complete stop.
in rain, snow or ice your tires have much less traction, and therefore need more braking distance.
Decrease ..
This statement is not accurate. In reality, when speed is doubled, the braking distance is quadrupled, not doubled, assuming all other factors remain constant. This is because the braking distance is directly proportional to the square of the initial speed.
Perception Distance, Reaction Distance and Braking Distance
Perception Distance + Reaction Distance+ Braking Distance.
Perception Distance + Reaction Distance+ Braking Distance.
