The speed; the quality of the braking system; the mass of the car; the time it takes the driver to notice a danger. The speed is especially important; other things being equal, braking distance is proportional to the square of the distance. That means that at twice the speed, the car will move 4 times as far while it brakes.

Why should you drive a car a greater distance ahead of a truck than behind it?
Because a truck is heavier than your car, it takes longer to stop than you do. If you drive closely ahead of a truck you are asking for trouble. If you have to stop suddenly, there is no way they are going to be able to stop as quickly as you, even if they see you stop. A truck may also roll right over you instead of just rear-ending you, and flatten your car like a pancake. Moral of the story - keep a safe distance from trucks!
Why is it easier to stop a car than a train?
Because a car weighs a lot less than a train - therefore it takes less force to stop the car.
What is meant by the stopping distance in a car?
It means the minimum distance the car moves between the time the driver decides to stop and the time the car actually stops. The distance can never be zero, and any pedestrian or animal who happens to be crossing in front of the car at a distance less than the stopping distance is simply out of luck.
What Two factors that affect the distance taken for a toy car to stop?
Air resistance against the car as it travels and the friction of the wheels against the ground slows it down and so reduces the toy car's potential travelling distance The weight of the car\on the car, the slope of the ramp and the material the car lands on or on the ramp
2 factors that affect the distance taken for a toy car to stop after rolling down a ramp?
Gravity and friction !
What is the element of stopping distance?
Total stopping distance is the thinking distance (The distance it takes for your brain to process the event and decide to stop the car) and the stopping distance (The distance it takes to stop the car once deceleration has begun) added together.

Total stopping distance equals the time in inches it takes you to hit the brakes plus how many yards it takes to actually stop the car?
true
Speed of car?
(distance the car travels) divided by (time it takes to cover that distance)
What is braking distance composed of?
Braking distance is usually measured by how fast you can stop at 60mph, 60-0, the make of a car is the factor of the stopping distance, each car varies. Your car can have disc brakes or drum brakes or both. Disc brakes are more effective than drum brakes. But braking distance is usually showed by how many feet it takes to stop from 60mph
What does your total stopping distance includes?
The total stopping distance includes the perception distance, reaction time and braking distance. The distance that your vehicle is traveling and then pressing on the brake after seeing a hazard, is the total stopping distance.
How many times more distance does it take to stop when speed is doubled?
Assuming a constant, linear deceleration, it takes four times the distance to stop when you double your speed. Using the formula v2 = u2 + 2as where v is final speed u is initial speed a is acceleration s is distance We can rearrange the formula to solve for s giving: s = (v2 - u2)/2a If we are finding the distance to that it takes to stop, the final velocity will be 0. Therefore distance to stop is given by s = -u2/2a Now we will look at the distance it takes to stop when speed is doubled. This will make our initial speed 2u. s = -(2u)2/2a = -2u2/a Comparing the two, we can see that when initial speed is doubled, it takes four times the distance to stop. (While it may look strange in the formula to have a negative sign in a distance measurement, remember that the car is decelerating, giving a negative acceleration. This means that the overall expression for distance will be positive.)
How many feet would it take for a compact car with good brakes going 45 mph to stop?
It takes a minimum of 135 feet for a car to stop at 45 miles per hour. The wear of the tires makes a difference in the distance too.
It take more force to stop a train than a car?
It takes less force to stop a train than to stop a car.
The total distance in which you will be able to bring your car to a stop includes the?
Reaction time AND breaking distance
What sort of things affect stopping distance when in car?
* The speed that the car is travelling at * Whether the road surface is wet - lessens friction so takes longer to slow down * The reaction time of the driver - the time it takes to process the information of needing to stop and actually doing it
