Friction is both our friend and also our foe ... isn't it strange?? sometimes we need it and sometimes not. like for eg: we need friction to hold things, to walk and to do many other things while sometimes it causes problems like it wastes energy, causes wear and tear ... hence it is our friend and also our enemy. 

HOPE it helped..

 Friction is a FRIEND.

Without friction, we will not be able to live as good as we are living. We cannot walk, run, hold things. Our vehicles will not stop at all easily.

The bad effects of friction like waste of energy, wear and tear heat etc.

But we can overcome the bad effects and manage friction to our benefit. But without friction life is VERY difficult. So friction is a FRIEND.
