What braking distance depends on
What braking distance depends on
How effective the braking force is
Effect of vehicle speed on braking distance
Effect of vehicle speed on braking distance
Faster speed = longer braking distance
Effect of wet/icy roads on braking distance
Effect of wet/icy roads on braking distance
They decrease friction, increase braking distance
Effect of worn tyres on braking distance
Effect of worn tyres on braking distance
They reduce friction, increase braking distance
Effect of worn brakes on braking distance
Effect of worn brakes on braking distance
They reduce braking force, increase braking distance
Why wet/icy roads increase braking distance
Why wet/icy roads increase braking distance
Lower friction between tyres & road, causing skidding
Why worn tyres increase braking distance
Why worn tyres increase braking distance
Reduced tread lowers friction, causing more skidding
