state and explain how one road condition affects the breaking distance of the car.use ideas about friction in your answer.
Answers
Answer:
Braking distance involves TWO pairs of forces … both friction.
One is the contact between the surfaces within your “brakes” to stop the wheels from turning. This does NOT stop the car. Cars with wheels locked have skidded into all kinds of trouble. This force from the contact surface in the brakes was set when you leave home.
The second pair of forces is between the tire tread and the road surface. Tires may be fixed; but the road surface, concrete/gravel/ice, certainly can vary.
The coefficient of friction is a variable dependent on the surfaces that may be slipping.
