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.

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. There are several forms of friction. One of the simpler characteristics of sliding friction is that it is parallel to the contact surfaces between systems and is always in a direction that opposes motion or attempted motion of the systems relative to each other.

Coefficient of friction depends upon

When we throw a ball on the floor, it starts moving with some velocity. Instead, the ball stops after moving a certain distance, so a force must be acting on it. Friction is defined as the resistance offered by the surfaces that are in contact when they move past each other. Friction provides traction that is needed to walk without slipping. Friction is helpful in most cases. However, they also offer a great measure of opposition to the motion.
