How is force reduced by increasing the distance to stop?
When a force is applied to the brakes of a vehicle, there is work done by the friction between the brakes and the wheel.
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 ..
What are the 4 factors involved in stopping distance?
The total stopping distance of a vehicle is made up of 4 components.Human Perception Time.Human Reaction Time.Vehicle Reaction Time.Vehicle Braking Capability.
What three components make up total stopping distance?
Total Stopping Distance is the sum of the perception distance, reaction distance and braking distance. Once a driver perceives a need to slow or stop, a small amount of time passes. The time it takes to react and come into the correct braking position is the reaction distance.
What is the relationship between speed and stopping distance?
A faster speed increases both thinking and braking distance, increasing the total stopping distance. You might be asked to look for patterns in car stopping distances, and how they change with the speed of a car.
Does mass affect stopping distance?
How does Mass affect the Braking Distance of a Car? The braking distance of a car increases as the mass increases. doubling the mass changes the braking distance of a car. … The brakes of the car apply the same force of 1500N.
What is the most important factor in a car’s stopping distance?
The weight of your car can also impact braking distance. One of the most significant factors that determines braking distance, however, is the surface of the road. Slippery road conditions, such as when it is wet, can increase the braking distance of your car by 75 percent and more.
What are the six factors that can affect total braking distance?
Factors that affect braking distance include “driver ability, speed, vehicle condition, roadway surface, hills, and weight of vehicle’s load”. You can control speed, ability, and the weight of the vehicle’s load.
What are 5 influencing factors of stopping distances?
There are five primary environmental factors that can impact stopping distance, and knowing how to respond to them is key to controlling your vehicle….HillsThe total weight of the truck and its load.The length and steepness of the downhill grade.The weather and road conditions.
What are the four factors that affect braking distance?
Braking distancepoor road and weather conditions, such as wet or icy roads.poor vehicle conditions, such as worn brakes or worn tyres.a greater speed.the car’s mass – more mass means a greater braking distance.
What is the stopping distance in icy conditions?
When driving in conditions of ice and snow the Highway Code advises your braking distance could be TEN TIMES higher than on a dry road. That means if you are travelling at 70 MPH on an icy road it could take you up to 771m to stop your car. That is the equivalent of half a mile or the length of 8 football pitches.
What are the factors affecting stopping distance?
10 things that can affect your stopping distanceSpeed. Your stopping distance is actually made up of two factors – thinking distance and braking distance. … Brakes. … Tyre Pressure. … Tyre Wear. … Tyre Quality. … Road Conditions. … View of the Road. … Distractions.More items…•
How is stopping distance calculated?
Techniques to remember stopping distances All you need to do is multiply the speed by intervals of 0.5, starting with 2. That’ll give you the stopping distance in feet, which is acceptable for the theory test. … There are 3.3 feet in a metre – so divide the distance in feet by 3.3 to get the stopping distance in metres.
How do you reduce stopping distance?
Let’s have a look at these 10 things that can help you do that.Tap on speed. Stopping distance is largely divided into two types — thinking distance and braking distance. … Maintain brakes. … Tyre pressure. … Uneven tread wear. … Tyre quality. … Road conditions. … Road view. … Distractions.More items…•
How do you calculate stopping distance in mph?
In a non-metric country the stopping distance in feet given a velocity in MPH can be approximated as follows:take the first digit of the velocity, and square it. Add a zero to the result, then divide by 2.sum the previous result to the double of the velocity.
What is stopping distance in physics?
stopping distance = thinking distance + braking distance. This is when: thinking distance is the distance a vehicle travels in the time it takes for the driver to apply the brakes after realising they need to stop. braking distance is the distance a vehicle travels in the time after the driver has applied the brake.
Why does stopping distance depend on road conditions?
Once the brakes are applied, the car begins to slow to a stop. The distance traveled by the car during this time is known as the braking distance. The braking distance is dependent upon the original speed of the car, the road conditions, and characteristics of the car such as its profile area, mass and tire conditions.
