Kinetic friction opposes the relative motion between two surfaces that are in contact and are slipping against each other.ahmed emad said:friction is causes the circular motion in the car around a curve, and if we draw free body diagram we will see the friction force must be opposite the car motion so the force of friction not toward to the center of the curve ,so the force of friction must be not the centripetal force ,mustn't it?
Friction is the force that resists the motion between two surfaces in contact. In the case of a car going around a curve, the friction between the tires and the road helps to maintain the car's trajectory and prevent it from sliding off the road.
If there is not enough friction between the tires and the road, the car will not be able to maintain its trajectory and may slide off the road. This can lead to loss of control and potentially cause an accident.
Yes, the type of tires can greatly affect the amount of friction between the tires and the road. Tires with a larger surface area and better tread patterns can provide more friction, making it easier to navigate around curves.
Yes, there is a maximum speed at which a car can safely go around a curve based on friction. This is because the amount of friction is dependent on the weight and speed of the car, and going too fast can reduce the amount of friction available to keep the car on the road.
Drivers can adjust their driving by reducing their speed while going around a curve, especially if the road is wet or slippery. They can also ensure that their tires are properly inflated and have good tread to maximize the amount of friction between the tires and the road.
