The formula for the coefficient of kinetic friction is given by; &181;k,r Fk,r N. Where, Fk,r is the force of rolling friction . N is the normal force, sometimes its denoted by . The Normal force has the same magnitude as the weight. Its represented by the equation; N m x g. f m a. N 2 m g. Here g is the acceleration due to gravity and N 2 is the normal reaction. As we know that if the static frictional force f is applied on the block of mass m, then the same frictional force f is applied by the mass m on the block of mass Mbut in the opposite direction. As the mass M has gained an acceleration, so we can apply. The coefficient of static friction is a scalar quantity and denoted as s.

In the case of an object resting upon a flat table (unlike on an incline as in Figures 1 and 2), the normal force on the object is equal but in opposite direction to the gravitational force applied on the object (or the weight of the object), that is, , where m is mass, and g is the gravitational field strength (about 9.81 ms 2 on Earth). The normal force here represents the force applied by. f m a. N 2 m g. Here g is the acceleration due to gravity and N 2 is the normal reaction. As we know that if the static frictional force f is applied on the block of mass m, then the same frictional force f is applied by the mass m on the block of mass Mbut in the opposite direction. As the mass M has gained an acceleration, so we can apply.

Static Friction is friction which is experienced when an object is placed on a surface. And, Kinetic friction is due to the movement of an object on a surface. Friction is well characterized by the coefficient of friction and is explained as the ratio between the frictional force and the normal force. This helps the object to lie on a surface.

Friction Force F frict. The friction force is the force exerted by a surface as an object moves across it or makes an effort to move across it. There are at least two types of friction force - sliding and static friction. Though it is not always the case, the friction force often opposes the motion of an object.
