Friction is reduced by adopting the following methods -
1) By polishing the surfaces.
2) By applying oil or grease on the surfaces ( or by lubrication)
3) By sprinkling a soft, slippery fine powder on the surfaces as we do on our carrom board.
4) By using wheels, ball-bearings or roller-bearings in machines.
5) By streamlining the body of an object like those of aeroplanes, rockets, ships, etc. Birds and fish also have streamlined bodies.
