Example of where you need friction?
The breaks on your car require friction to make the car stop. Friction between the souls of your shoes and the ground keeps you from sliding.
When do you need to increase friction?
We Increase Friction when we are stopping a car, bike or when slowing down to a way up.
Why is it to stop a car on a wet road?
it is harder because there is less friction with lubrication -which is what water is -and you need friction for the breaks to work
When is friction desirable?
Friction is desirable on your tyres and brakes. Tyres need to grip the road, to push the car forward, stop and go round corners. Brakes need friction to stop the wheels turning.
Why does a car need a forwards force to keep moving?
Resistance from air and friction.
Why is it harder to stop a car on a wet road?
it is harder because there is less friction with lubrication -which is what water is -and you need friction for the breaks to work
What is a feature of a car that increases friction?
the front boot of the car increases the friction on the car
How much torque that car wheel need?
Sufficient to overcome the inertia and friction of the vehicle.
Where would you need lots of friction?
you need a lot of friction when driving a car, your brakes on your bike needs a lot of friction , to slow down , friction is where two things rub together and make heat to make things slow down or become faster.
Do car brakes reduce friction?
Friction is what makes the brakes stop the car.
How does friction change how far a car goes?
Friction does work to slow down the car. Thus, the more friction there is, the less distance a car can go.
Does driving on ice need friction?
Yes. If there wasn't any friction the wheels would just spin w/o the car going anywhere.
