Coefficient of friction depends upon

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 Mar 19,

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 nature of the surface. 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. Therefore, the c oefficient of friction is a measure of the amount of friction existing between two surfaces. Byju's Answer. What are the factors on which coefficient of friction depends?

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. It is commonly thought that the static coefficients of friction are higher than the dynamic or kinetic values. This is a very simplistic statement and quite misleading for brake materials. With many brake materials the dynamic coefficient of friction quoted is an "average" value when the material is subject to a range of sliding speeds, surface pressures and most importantly operating temperatures. If the static situation is considered at the same pressure, but at ambient temperature, then the static coefficient of friction is often significantly LOWER than the average quoted dynamic value. Kinetic or sliding frictional coefficients are used with relative motion between objects. Static frictional coefficients are used for objects without relative motion. Note that static coefficients are somewhat higher than the kinetic or sliding coefficients.

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.

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.
