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.
What else can I help you with?
Are the forces on the car in balance after you stop pushing?
No, the forces are not in balance after you stop pushing. When the car is stationary, the force of friction between the tires and the ground opposes the force applied to the car when you were pushing it.
What is an example of force acting on a moving car?
An example of a force acting on a moving car is friction between the tires and the road. This friction force allows the tires to grip the road surface and generate the necessary traction for the car to accelerate, decelerate, or make turns.
When is friction useful?
Friction is useful in various ways, such as enabling us to walk and grip objects. It is crucial for vehicles to move on roads and for machines to operate effectively. Friction also helps in slowing down moving objects and preventing slipping or sliding.
What is an example of not useful friction?
An example of not useful friction is the friction between the tires of a car and the road surface when trying to accelerate. This friction wastes energy in the form of heat and wears down both the tires and the road, without serving a beneficial purpose in this context.
Describe a situation in which static friction is useful?
Static friction is useful when trying to prevent slipping or sliding of objects on a surface. For example, static friction allows car tires to grip the road, enabling the vehicle to accelerate and stop effectively. This type of friction is crucial for stability and control in various everyday activities.
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?
How is force of friction useful?
driving a car
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 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,
Are the forces on the car in balance after you stop pushing?
No, the forces are not in balance after you stop pushing. When the car is stationary, the force of friction between the tires and the ground opposes the force applied to the car when you were pushing it.
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.
2 examples where friction is useful?
Wooden match and car brakes

How does friction decrease the acceleration of a car?
friction decreases the acceleration of a car by creating a greater force which pushes against the acceleration force. the friction is a force, but more of it means that whatever is pushing against it ( acceleration in this case) is made smaller.
