Friction a Necessary Evil If there is no friction between any two surfaces in contact, then the present day civilization will be no more- as we cannot even walk properly on the earth.

Because without friction we can't walk properly..... we can't ride cycle properly...
If there is no friction between any two surface in contact, then the present day civilization will be more as -we cannot even walk properly on the earth. There will be no fabrics and garments, no construction of buildings and no furniture, evwn no cooking and no vehicles.so friction is necessary. But too much friction causes a heavy loss of energy, wear and tear of machinery.Thus ,the efficiency of machines will decrease tremendously. So, it is rightly said that friction is a necessary evil.
Friction plays an important part in daily life.
1-A motion cannot be started. We cannot walk on a frictionless surface.
2-A motion cannot be transferred. In a rotating machine wheel by motor wheel by a belt cannot be done if there is no friction between the belt and the wheels.
