Question

Lets assume that a block has been kept on a rough floor. We started applying a variable force "F" (assume that the force is being increased) on the block.

Draw the graph of Frictional force (Y axis) vs Applied Force (X axis) !

Also tell the peculiar change observed in the latter part of the graph !

Answer 1

Explanation:

After a certain value of frictional force ( static frictional force) the value of the friction force became constant despite of increasing applied force.

Answer 2

Lets assume that a block has been kept on a rough floor. We started applying a variable force "F" (assume that the force is being increased) on the block.  Draw the graph of Frictional force (Y axis) vs Applied Force (X axis) !  Also tell the peculiar change observed in the latter part of the graph !

$\bf{----------------------\:@BrainlyKingdom}$

Applied force is a variable force.

There are three types of friction forces :

• Static friction, Limiting friction and Kinetic friction

Some points on friction forces :

• Static friction :  Static friction is an self adjusting force. $\sf{Static\:Friction\::\:F_{s} \leq \mu_{s} N}$

• Limiting friction : It is the maximum friction force between two static surface.  If we apply force slightly more than limiting friction then body start to move. $\sf{Limitng\:friction\::\:F_{l}=F_{\max }=\mu_{s} N}$

• Kinetic friction : Friction force between two moving surfaces.  Kinetic friction is not self adjusting force. $\sf{Kinetic\:friction\::\:F_{k}=\mu_{k} N}$

Kindly Refer to Attachment for Graph !

In graph you can see  , Friction force is rising from zero to maximum and then decreased little bit and then remained constant
