Understanding Breaking Distance

What does breaking distance refer to in vehicle dynamics?

• The distance a vehicle travels from the time the brakes are applied until it comes to a complete stop.

• The distance a vehicle travels before the brakes are applied.

• The total distance a vehicle travels while the accelerator is pressed.

• The distance covered by a vehicle after the engine is turned off.

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

• Vehicle speed

• Vehicle weight

• Tire condition

• Color of the vehicle

The breaking distance of a vehicle increases with the square of its speed. If the breaking distance at 20 km/h is 4m, what is the breaking distance at 40 km/h?

• 8m

• 16m

• 32m

• 64m

What role does the condition of a vehicle's tires play in breaking distance?

• No role, as tires do not affect breaking distance.

• Worn-out tires increase the breaking distance.

• New tires increase the breaking distance.

• Only the color of the tires affects breaking distance.

How does rain affect the breaking distance of a vehicle?

• It has no effect.

• It decreases the breaking distance.

• It increases the breaking distance.

• It first decreases then increases the breaking distance.

What is the effect of a heavier vehicle load on the breaking distance?

• It decreases the breaking distance.

• It has no significant effect.

• It increases the breaking distance.

• It first increases then decreases the breaking distance.

Anti-lock Braking Systems (ABS) are designed to:

• Increase the breaking distance to make stopping smoother.

• Decrease the vehicle's speed instantly.

• Prevent the wheels from locking up and skidding, reducing the breaking distance.

• Increase the vehicle's grip on the road without affecting the breaking distance.

If the initial speed of a vehicle is doubled, how does this affect the theoretical breaking distance, ignoring other factors like road conditions?

• It remains the same.

• It doubles.

• It quadruples.

• It is halved.

What is the typical effect of road conditions, such as being wet or icy, on a vehicle's breaking distance?

• They have no effect.

• They decrease the breaking distance.

• They increase the breaking distance.

• They first decrease then increase the breaking distance based on the temperature.

Why is it advised to increase the following distance between vehicles under poor weather conditions?

• To decrease the breaking distance.

• To allow more time and space for breaking due to increased breaking distance.

• To enjoy the scenery.

• To save fuel.
