Forces And Braking

Question 1

The greater the speed of a vehicle…

Answer 1

The greater the braking force needed to stop it in a certain distance

Question 2

What can a drivers reaction time be affected by?

Answer 2

Tiredness, drugs and alcohol

Question 3

What is the stopping distance of a vehicle

Answer 3

Sum of the distance the vehicle travels during the drivers reaction time (thinking distance) and the distance is travels under the braking force

Question 4

What happens when the brakes of a vehicle are applied

Answer 4

Work done by the friction force between the brakes and the wheel reduces the kinetic energy of the vehicle and the temp of the breaks increase

Question 5

What can a vehicles braking distance be affected by

Answer 5

Adverse road and weather conditions

And poor condition of vehicle

Question 6

When a vehicle travels at a steady speed the resistive forces do what

Answer 6

Balance the driving force
