Coefficient of friction depends upon

The coefficient of friction is defined as the ratio of the force of friction acting between two objects and the force which is pushing them together. The value of the coefficient of friction varies from zero to one.

The coefficient of friction depends on the material and roughness of the two surfaces in contact. As long as the normal force is constant, the maximum possible friction does not depend on the area of the surfaces in contact.

The coefficient of friction depends on the material and roughness of the two surfaces in contact. As long as the normal force is constant, the maximum possible friction does not depend on the area of the surfaces in contact. Last updated on Apr 12, The application process was started on 1st December Get Started. English Hindi. This question was previously asked in. Attempt Online. Area of contact only Nature of surface only Both a and b None of these. Explanation: The coefficient of friction depends on the material and roughness of the two surfaces in contact. Law of limiting friction for dry surfaces: When two bodies are in contact, the direction of the force of friction on one of them is opposite to the direction in which this body has the tendency to move. The frictional force is independent of the area of contact of the surfaces. When one body is just on the point of sliding over the other body, the maximum force of friction is being exerted; This is called the limiting friction.

Friction is a force that is around us all the time that opposes relative motion between systems in contact but also allows us to move which you have discovered if you have ever tried to walk on ice. While a common force, the behavior of friction is actually very complicated and is still not completely understood. We have to rely heavily on observations for whatever understandings we can gain. However, we can still deal with its more elementary general characteristics and understand the circumstances in which it behaves. Friction is a force that opposes relative motion between systems in contact. One of the simpler characteristics of friction is that it is parallel to the contact surface between systems and always in a direction that opposes motion or attempted motion of the systems relative to each other. If two systems are in contact and moving relative to one another, then the friction between them is called kinetic friction.

Now, it's time to include this very real force and see what happens. What are the forces of static and kinetic friction? Parking your car on the steep hills of San Francisco is scary, and it would be impossible without the force of static friction.

The friction force is the force exerted by a surface when an object moves across it - or makes an effort to move across it. For an object pulled or pushed horizontally the normal force - N - is simply the gravity force - or weight :. Kinetic or sliding frictional coefficient only when there is a relative motion between the surfaces.
