Which of the following factors has direct influence on the stopping distance of the passenger car?
Description
In calculations of a vehicle's stopping distance, the element of mass does not feature.
Explanation
Correct answer: The speed and the condition of the road surface.
The key factor influencing the stopping distance is the vehicle's speed. This distance increases approximately in proportion to the square of the speed, which means that doubling the speed results in an approximately fourfold increase in the stopping distance. That is why it is so important to adjust your speed to the prevailing road conditions.
