Thinking distance and breaking distance 1 of 7 What is thinking distance determined by? The drivers reaction time? 2 of 7 What is thinking distance The distance car travels from moment they see a problem to when they put their foot on the brake 3 of 7 What is braking distance? The moment the foot goes on brake till the car stops 4 of 7 Name two thinks thinking distance is affected by? Worn tyres and brakes/ If roads are wet or icy 5 of 7 What happens to the to a car if the wheels lock? Why? Car slides, kinetic energy converted into thermal (heat) energy. Because of fricton between tyres and road 6 of 7 What causes thermal (heat) energy in the brakes by friction? The kinetic energy of the car 7 of 7
