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 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 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.

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. In addition, about 20 per cent of the engine power of automobiles is consumed in overcoming frictional forces in the moving parts. In the next section, let us go through some of these factors. Friction is a force that is dependent on external factors.
