Gravity if going uphill. Friction.
There are many examples. The simplest ones would be walking or driving a car. Without friction it would be impossible to walk or drive, as there would be no surface to push away from. Wheels of a car would just spin and the car would remain stationary. Think about driving on ice (ice still have friction, its just lower).
Friction tends to slow things down -- friction, particularly within the spokes of the wheels, is, after all, the reason why a car cannot run forever on one tank of gas. However, friction is also necessary for a car to move. When a car's wheel pushes against the ground, it is the force of friction that pushes back against it; according to Newton's Third Law of Motion, there is an equal and opposite reaction. When there is no friction to push against, there is no opposing force to push the wheel of the car along, which is why it is hard do drive along a slippery icy road.
Because if there is no friction between the wheels and the asphalt the car would simply spin out. Unable to move at all on a friction-less surface. In fact, it's so important racecars have upsidedown wings to push the car into the ground to get better friction. Which when we're talking about car wheels is also called traction.
It would not be able to move. The push of the engine driving the car forward depends on friction between the tyres and the road. If something else started it moving, the brakes couldn't work to stop it.
how does friction help car tyres?
Gravity if going uphill. Friction.
When the wheels of a car turn, friction causes the wheels to push back on the road, which in turn causes the road to push the car forward. Without friction the wheels would just spin in place. You can sometimes see this occur on icy roads, where there is very little friction.

friction helps the movement of the car by allowing it to move easily and smoothly. -------------- Friction between the tires and the road propels the car forward and steer it. Friction in the brakes helps control the motion.
yes
The brakes on your car are a good example.
When the tires have no friction, they are not gripping on anything, therefore they spin without pushing the car forward,

An example using a car:Advantage: friction on car tires makes the car stop. Without friction, the car would continue without stopping (e.g. such as mass in space once given a push in one direction)Disadvantage: friction on car tires means more energy is required to propel the car forward = more gas is required for a trip.
Through push and pull and the other force is friction
