Stopping Distance

___________ distance is the total distance the vehicle

travels when you add the driver’s reaction time (thinking distance) and

the distance a vehicle travels under the braking force (braking distance)

• thinking

• stopping

• braking

___________ is time it takes a person to process that they need to stop their vehicle.

• thinking distance

• stopping distance

• braking distance

______________ is the distance your car will travel once you hit the brakes before it comes to a complete stop.

• thinking distance

• stopping distance

• braking distance

For a given braking force, the greater the speed of the vehicle, the greater the

stopping distance.

• true

• false

If one car is travelling at 10m/s and the second car, of the same mass, is travelling at 15 m/s, which car will have the greatest stopping distance? (assuming that both have exactly the same reaction time)?

• car 1

• car 2

• both will take the same amount of time

• braking

What is the relationship that you can see between speed and total stopping distance?

• The faster you are travelling, the shorter the total stopping distance

• The slower you are travelling, the longer the total stopping distance

• Thinking distance increases a lot, and so does speed

• The faster you are going, the longer the total stopping distance

Thinking distance increases the same amount as the braking distance as the speed increases.

• true

• false
