We call Friction a necessary evil because we need it sometimes and in some cases, we won't need it. Friction is a necessity -:
(1) It is due to friction between the ground and the feet that we are able to walk. (2) The brakes of a vehicle cannot work without friction. (3) Various parts of a machine are able to rotate because of friction between belt and pulley. (4) The tyres of vehicles are made rough to increase friction. (5) Nails and screws join various wooden parts due to friction. (6) In the absence of friction, it will not be possible to write on paper with a pen or pencil. Friction is evil -: (1) Wear and tear of machinery are due to friction. (2) A large amount of power is wasted in overcoming friction and the efficiency of the machines decreases considerably.
