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. The force of friction is dependent upon the types of materials of the two bodies in contact. The limiting frictional force is proportional to the normal force that acts between the bodies in contact.

When a body is in motion, it has resistance because the body interacts with its surroundings. This resistance is a force of friction. Friction opposes relative motion between systems in contact but also allows us to move, a concept that becomes obvious if you try to walk on ice. Friction is a common yet complex force, and its behavior still not completely understood. Still, it is possible to understand the circumstances in which it behaves. The basic definition of friction is relatively simple to state. Friction is a force that opposes relative motion between systems in contact.

Coefficient of friction depends upon

A coefficient of friction is a value that shows the relationship between two objects and the normal reaction between the objects that are involved. It is a value that is sometimes used in physics to find an object's normal force or frictional force when other methods are unavailable. The coefficient of static friction is the friction force between two objects when neither of the objects is moving. The coefficient of dynamic friction is the force between two objects when one object is moving, or if two objects are moving against one another. The coefficient of friction is dimensionless and it does not have any unit. It is a scalar , meaning the direction of the force does not affect the physical quantity. The coefficient of friction depends on the objects that are causing friction. The value is usually between 0 and 1 but can be greater than 1.

Delhi Police Constable. Cochin Shipyard Draftsman Trainee. India Post Mail Guard. Static friction does not depend upon the area of the surfaces in contact because it only depends upon the nature of the surfaces of the material. Bombay High Court Peon. Which of these statements is correct for inelastic collision? 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 the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.
