Why do we sprinkle fine powder on the carrom board and grease your bicycle moving parts?
Answers
We sprinkle powder on carrom board to make the surface of the board smooth. This reduces the friction between the surface of the carrom board, the striker and the coins. As a result, the coins and the striker can move easily on the carrom board.
A bicycle mechanic and motor mechanic uses grease between the moving parts of these machines to reduce friction and increase efficiency.

Grease smooths movments in parts. friction makes the surface of the moving parts of the cycle irregular. they need to be equalised so that the cycle can move smoothly. thus they use grease as a lubricant to equalise the surface.
