The braking distance also depends on the speed of the car, the mass of the car, how worn the brakes and tyres are, and the road surface. ... A faster speed increases both thinking and braking distance, increasing the total stopping distance.

How does the speed of a vehicle affect the braking distance of the vehicle?
Braking distance is the time it takes for your car to come to a complete stop after you've hit your brakes. When you double the speed of your car, your braking distance quadruples. As shown below, every time you double your speed, you multiply your braking distance by four.
How does vehicle speed affect braking force?
The faster a vehicle travels, the greater the braking force needed to stop it in a certain distance. A greater braking force produces a greater deceleration .
Why does the braking distance increase with speed?
The braking distance increases four times each time the starting speed doubles. This is because the work done in bringing a car to rest means removing all of its kinetic energy. So for a fixed maximum braking force, the braking distance is proportional to the square of the velocity.
How does speed affect distance?
The faster an object is moving, the longer the distance it takes to stop. If a vehicle's speed doubles, it needs about 4X's the distance to stop. If a vehicle's speed triples, it needs up to 9X's the distance to stop.
What increases braking distance?
The braking distance of a vehicle can be increased by: poor road and weather conditions, such as gravel, or wet or icy roads - less friction between tyres and the road. ... more mass in the vehicle (extra passengers for example) - the braking friction has to work for a greater distance to remove the larger kinetic energy.
What two factors affect braking distance?
Braking distance is the distance traveled after you apply the brakes. It depends on two factors: speed and drag.
What is the relationship between speed and stopping distance?
The stopping distance is proportional to the square of the speed of the vehicle.
How does friction affect braking distance?
A friction reduction from 0.8 to 0.4 or from 0.6 to 0.3 means a doubling of the braking distance. From 0.8 to 0.2 a four time longer braking distance must be reckoned. The winter services should try to avoid weather-related friction values dropping below 0.6 – if possible.
How do speed traction and gravity affect braking distance?
Gravity affects your speed when you drive uphill and downhill. Traction relates to gravity in that it is the result of friction between the road and your tires caused by the weight of the car (the pull of gravity). ... Gravity will cause you to go faster and increase your stopping distance.
Can braking distance be accurately predicted from mph?
From our answers in part (a), we see that the speed for a braking distance of 500 ft is between 60 mph and 90 mph. Estimates within this range can vary, though based on the computations, it is reasonable to predict a velocity closer to 90 than to 60.
Does distance increase with speed?
c. An increase in speed increases reaction distance but does not affect braking distance.
What is the relationship between speed and distance covered by car?
This equation shows the relationship between speed, distance traveled and time taken: Speed is distance divided by the time taken. For example, a car travels 30 kilometers in 2 hours. Its speed is 30 ÷ 2 = 15km/hr.
Is speed directly proportional to distance?
The basic formula says Speed= Distance/Time . From this formula, it is evident that speed is directly proportional to distance and inversely proportional to time.
