Thinking & Breaking Distance

Question 1

The dirver’s reaction time

Answer 1

The slower the reaction tiem, the further the car moves before the brakes are pressed. Anything that increases reaction times will increase the thinking distance.

Question 2

The speed of the car

Answer 2

If the car is moving faster, the car will have moved further whilst the driver reacts.

Question 3

The speed of the car

Answer 3

The faster moving car needs more force to slow it down. Therefore, it takes a longer distance to stop.

Question 4

Friction

Answer 4

Then braking distance will be shorter when there is more friction. There is less frction on wet or icy roads. This means the breaking distance will be longer.

Question 5

The mass of the car

Answer 5

It takes more force to stop a heavier car. This increases the braking distance.

Question 6

The condition of the brakes and tyres

Answer 6

Worn brakes and ryres will increase the braking distance because there is less friction force.
