Worked Solution & Example Answer:The thinking distance and braking distance for a car vary with the speed of the car - AQA - GCSE Physics - Question 1 - 2021 - Paper 1
Step 1
Explain the effect of two other factors on the braking distance of a car.
Answer
-
Poor Condition of Tyres: When tyres are worn or not adequately inflated, the friction between the tyres and the road surface decreases. This can significantly impair the braking force, resulting in a longer braking distance as it takes more time for the car to come to a complete stop.
-
Increased Mass of the Car/Passengers: A heavier car requires a greater braking force to achieve the same deceleration as a lighter car. This is due to the increased kinetic energy that must be dissipated during braking, thereby increasing the braking distance.
