If you are behind a car, about to push it forward from a resting position, you will need to exert a force on the car to accelerate it from resting position. While you are pushing against the car, however, there will be a reaction force pushing back at you. In order to produce a large net force against the car without being pushed backward yourself, you need to increase the friction of your feet against the ground...so that the frictional force between your feet and the ground prevents you from sliding backward. The combinations of the frictional force and your force pushing forward against the car will cause the car to move forward. The frictional force of the car being moved from resting position also has to be overcome, of course.

Where does friction accure?
when you are driving a car and it is pushing it back
When is friction useful?
Friction Is Useful For Lots Of Things Like Walking Or Riding a Bike
How does air resistance allow the car to go faster?
The air creates friction, just like the ground. With less friction, the less pushing the car back.
What is an example of force acting on a moving car?
Somebody pushing the car; friction slowing down the car; gravity acting on the car (this is especially relevant if the car is going up or down a slope); the engine pushing the car forwards.
How friction can be both helpful and unhelpful?
On a car, friction is useful on the tyres and brakes. It is not required for the parts that rotate.
When can friction not be useful in a boat?
the friction from pushing the hull through the water is not useful as long as you're travelling.

Why are tyres useful friction?
how does friction help car tyres?
When Is Friction Useful and When Is Friction Not Useful?
Friction is useful when you are trying to stop a car, but not useful in the pistons of a car's engine (It makes them less efficient).
How is force of friction useful?
driving a car
How oes friction help unbog a car?
When the tires have no friction, they are not gripping on anything, therefore they spin without pushing the car forward,
Is pushing a useful friction or not useful?
a beluga whale! ive seen it before, bet ur tots jelly! feel the burn!

What is useful friction?
there is friction in your cars brake system and without that frictiuon there your car would roll away whenever it was on a hill so this is a good example of when friction is useful.
