Question

Friction is good or bad for us ? Why?

Answer 1

Friction is both good and bad for us.
Friction is good:-
*It is due to friction between our foot and ground,that helps to walk properly
*It is due to friction between our fingers and the pen,that helps us to hold it properly
*It is due to the presence of friction between the tyres of a car and the ground that helps us to drive a car
Friction is bad:-
*If there was no friction we don't need to pedal the cycle continuously
*If there was no friction we can easily push or pull furniture and other things

Hope this helps :)
