What factors does the stopping distance depend on?
The braking distance depends on many factors, the main ones being: - the speed at which the vehicle is traveling; ... - the condition of the brakes and tires of the vehicle; - the quick reflexes and driving skills of the driver, who must be able to brake without locking the wheels.
How is the driving license braking distance calculated?
The distance covered in the reaction time (about 1 second) can be roughly calculated by dividing the speed by 10 and multiplying the result by three (example at 45 km / h: 45/10 = 4,5x3 = 13,5 meters); while the stopping distance is calculated roughly by dividing the speed by 10 and multiplying the ...
How do you calculate total stopping space?
In an approximate way, the Stopping Space is calculated by squaring the tens of speeds or even by removing a zero from the speed and then multiplying by the same number, thus obtaining a distance expressed in meters.
How does the braking distance increase?
The braking distance also depends on: - the GRIP between the tire and the asphalt: it increases if the grip is low (for example if the road is wet or covered with snow) or if the wheels lock. - from the SLOPE of the road: it decreases uphill and increases downhill.
When does the total stopping space increase and when does it decrease?
Total stopping distance increases as speed increases; The total stopping distance increases if the road is covered with snow; The total stopping distance increases if the road is covered with mud; The total stopping distance increases if the tires are worn.

What does the total stopping distance mean?
The total stopping distance is the space a vehicle travels from the moment the driver senses a danger and therefore the need to stop until the vehicle comes to a complete stop. ... The reaction space therefore depends: on the speed
When does the stopping distance decrease?
The braking distance decreases if the wheels lock; The braking distance decreases on the downhill section of a bump; The braking distance increases if the road is uphill; The braking distance decreases if the road is downhill.
How many meters does it take to brake?
Theoretically, the minimum distance to be able to stop safely, expressed in meters, would be: 25 meters if you travel at 50 km per hour. 60 meters at 90 km per hour, 110 meters at 130 km per hour.
What factors affect the braking distance?
Nevertheless, among all those listed, the factors that have the greatest influence are the speed at which it is traveling, the deceleration of the vehicle and the coefficient of friction between the road surface and the tires. and gives the braking distance expressed in meters.
What is the braking distance?
"Braking distance is the distance a vehicle travels between the start of deceleration and stop."
How much do you travel in a second if you travel at 100 km / h?
So in one second, you travel about 14 meters if you are traveling at 50 km / h, about 28 m if you are traveling at 100 km / h, about 36 m if you are traveling at 130 km / h, and about 42 m if you are traveling at 150 km / h.
How is time calculated?If the velocity is equal to space over time, then:
- S = V x T. Space equals velocity multiplied by time.
- T = S / V. Time equals space over speed
How do you find the deceleration?
Hi Chiara, the formula for deceleration is that of acceleration with a negative sign. The resolution of the problem, however, is: 1) the formula for the average acceleration given speed and space is obtained from the following: s = (Vfinale ^ 2 - Viniziale ^ 2): 2a.
What is braking distance and who does it depend on?
It is the distance covered from the beginning of the braking to the stop of the vehicle. It depends on the speed: the higher the speed, the more it increases. It is not true that it depends on the reflexes of the driver (they only affect the reaction time).
How is the braking force calculated?
F * s = m * v2 / 2
where "F" is the braking force, "s" is space, "m" is the mass of the car and "v" is the speed at which the vehicle is moving. To give an example, we will always calculate the braking distance of a 1000 kg car traveling at speeds of 50 and 100 km / h, both on dry and wet asphalt.
What is the reaction space and who does it depend on?
The reaction time is usually around one second. Therefore the space covered in the reaction time is that covered from the moment of perception of a dangerous situation to that of the beginning of braking. It depends on the speed at which you are moving.
How is the braking time of a car calculated?
To calculate the emergency braking distance, the following formula is applied, assuming a dry road and tires in good condition: Emergency braking distance = ½ x (speed / 10 x speed / 10). In this case, traveling at 70 km / h will require 24,5 meters of braking distance.
How many meters does it travel before starting to brake?
Thus, the reaction space of a car traveling at 50 km / h is 14 meters, i.e. before braking starts, it travels a good 14 meters.
How many meters do you need to stop at 130 km / h?
In fact, at 130 km / h, braking takes about 169 meters; at 150 km / h, it takes 225 meters.
That the braking distance decreases in case of rain?
It is necessary to moderate the speed, avoid sudden maneuvers (steering, accelerating, braking) and keep in mind that, in case of rain or ice, the braking distance of the vehicle increases (therefore, the safety distance from the vehicle in front must be increased).
What does rough asphalt mean?
[rù-vi-do] adj. 1 Not uniform to the touch, rough, irregular (opposed to smooth): drawing paper r.
Is anyone driving under the influence of alcohol at risk of arrest?
There is a pecuniary sanction from € 1.500 to € 6.000, arrest from a minimum of 6 months to a maximum of one year and the ancillary penalty of suspension of the driving license from 1 to 2 years. In this case too, driving under the influence of alcohol is a crime and the driver risks being arrested.
What is the braking time?
it is equivalent to the distance traveled by the vehicle during the reaction time, that is, between the instant in which the driver perceives a danger to that of starting braking. By convention and calculation convenience, a reaction time of 1 second is considered.
What is the G-force in f1?
Formula 1 drivers are subjected to incredible forces when they brake: up to 6 times their weight. ... The number of gs represents the acceleration multiplied by the mass of the pilot as a result of the force to which it is subjected.
How do you find the final speed?
The circular speed of an object is calculated by dividing the circumference of the path to be traveled (the orbit) by the period of time it takes to travel it. Placing the formula on paper we will obtain the following equation: v = (2πr) / T.
