FRICTION:-The force opposed on any body which is in motion to reduce the motion is called friction.

There are three types of friction.they are:-

(1)Static friction(or)limiting friction.(fs)

(2)kinetic friction(or)dynamic friction.(fk)

(3)rolling friction.(fr)

fs=Us.N   for further information type the question and mail to the address.

ITS SIMPLE

 

 

ALWAYS TAKE FRICTION IN OPPOSITE DIRECTION OF MOTION ,............ BUT IN CASE OF ROTATIONAL U WILL HV TO ANALYZE THE PROBLEM

EX: CAR MOVING IN +X AXIS DIRECTION FRITCTION FORCE WILL ALSO ACT IN SAME DIRECTION OF MOTION

TO UNDERSTAND THIS

CONSIDER

THE WHEELS OF CAR AND SEE TANGENTIAL VELOCITY ITS TOWARDS -VE X AXIS

 

 

 

FRICTIONAL FORCE IS GIVEN BY

COEFFICENT OF FRICITON*NORMAL FORCE IN ANY CASE..............

IN CASE OF INCLINATION RESOLVE FORCES IN X AND Y DIRECTIONS

 

U CAN REFER TO HC VERMA SURELY IT WILL MAKE UR BASIC CLEAR
