Understanding Stopping Distances and Graphs

What is the stopping distance of a vehicle?

• The distance a vehicle travels while the driver is thinking about stopping

• The distance a vehicle travels after the brakes are applied

• The total distance a vehicle travels from the moment the driver decides to stop until the vehicle comes to a complete stop

• The distance a vehicle travels in one second

Which factor does NOT affect the braking distance of a vehicle?

• Road conditions

• Vehicle speed

• Driver's reaction time

• Tyre condition

How is thinking distance calculated?

• By multiplying the speed of the vehicle by the driver's reaction time

• By dividing the speed of the vehicle by the braking force

• By adding the speed of the vehicle to the braking distance

• By subtracting the braking distance from the stopping distance

Why is thinking distance important in driving?

• It determines the maximum speed a vehicle can travel

• It affects the total stopping distance and can prevent accidents

• It is used to calculate fuel efficiency

• It helps in determining the vehicle's acceleration

What does the slope of a speed-time graph represent?

• Distance travelled

• Acceleration

• Velocity

• Time

In a velocity-time graph, what does a horizontal line indicate?

• Constant acceleration

• Constant velocity

• Increasing velocity

• Decreasing velocity

Which of the following is a correct formula for calculating braking distance?

What is the primary purpose of emergency braking techniques?

• To increase the speed of the vehicle

• To reduce the stopping distance in an emergency

• To improve fuel efficiency

• To maintain a constant speed

Which of the following factors can increase the thinking distance?

• Wet road conditions

• Driver fatigue

• New tyres

• Lower vehicle speed

What does a steeper slope on a speed-time graph indicate?

• Slower acceleration

• Faster acceleration

• Constant speed

• Deceleration
