The stopping distance of a car depends on two factors...
thinking distance and braking distance
1 of 12
Under normal driving conditions, the thinking and braking distance depend on...
the speed of the car
2 of 12
When a vehicle travels at a steady speed the driving force from the engine is balanced by...
air resistance and other resistive forces
3 of 12
For a vehicle to slow down, one or both of the following have to happen...
the driving force from the engine must be reduced or the resistive forces must be increased
4 of 12
The thinking distance increases if the _________ increases
Reaction time
5 of 12
Reaction time increases if the driver is...
-tires -distracted -under the influence of alcohol/drugs
6 of 12
The braking distance is...
the distance taken to stop once the brakes are applied
7 of 12
The braking distance increases if...
-the car's brakes/tyres are in bad condition -the road and weather conditions are poor
8 of 12
The braking distance also increases as the __________ increases
Car’s speed
9 of 12
When the brakes are applied, ________ by the friction force between the brakes and the wheels
Work is done
10 of 12
When the brakes are applied and work is done, it ______ the kinetic energy of the vehicle
Reduces
11 of 12
When the brakes are applied and work is done, it ______ the temperature of the brakes
Increases
