Friction between a wheel and a road is essential for a vehicle's traction and control. It helps in maintaining grip to accelerate, decelerate, and turn effectively. The amount of friction depends on factors like the texture of the road surface and the quality of the tires.
By reducing the coefficient of friction between the brakes and the wheel OR between the road and the wheels.
Rolling friction occurs when an object rolls over a surface, resulting in less resistance compared to sliding friction, where two surfaces slide against each other. Rolling friction typically requires less energy to overcome than sliding friction.
The friction between the asphalt on the road and the rubber tires cause a screeching sound, due to the sudden stopping of the wheel motion. The sound is caused because the tire has overcome static friction, and is now in sliding friction between it and the road.
In a turn, the friction between the tires and the road provides the centripetal force needed for the car to turn. The steering wheel controls the direction of the car by turning the front wheels, but it does not provide the centripetal force itself.
friction is that force that opposes motion. for e.g friction between the road and your shoes prevent you from falling when you walk on the road.
It is difficult to move a cycle with the brakes on because the brakes create friction between the brake pads and the wheel, which resists the motion of the wheel. This friction reduces the efficiency of pedaling and makes it harder to propel the bike forward.
Sliding Friction
Examples of friction include rubbing your hands together to generate heat, the resistance between a car's tires and the road surface that allows it to brake, and the force that opposes the motion of a sled sliding down a snow-covered hill.
When driving because if there was no friction between the tires and the road, the vehicle would just slide of the road and crash.
A car skidding on an icy road will exhibit kinetic friction, which is the force that resists the motion of two surfaces sliding against each other. The low coefficient of friction between the icy road and the car's tires makes it easier for the car to skid.
