Question

draw the graph between applied and friction force

Answer 1

hope this helps you

Answer 2

Explanation:

Consider a case of a box on the surface of the table, on which force is applied.

In the part O to A:

Initially, as there is no force acting on the box, the frictional force is also zero.

As we start to apply force on box, static friction starts ($F_s$) to acts on the interface between the two surfaces of boc and table. More the force is applies, more is the static friction opposing the motion. Until a point is reached when force is equal to limiting friction

At the point A:

Point A is the limiting friction, which is the maximum frictional force generated between two static surfaces.

Beyond point A:

Kinetic friction starts to act and the value of the frictional force becomes constant after the box starts moving.

The value of  kinetic friction is less than the maximum static friction.
