Question

What would be the impact on friction if powder is sprinkled on the carrom board?

Answer 1

Hint: Friction is a force between two surfaces that are sliding, or trying to slide, across each other. It always works in the direction opposite to the direction in which the object is moving, or trying to move. Friction always slows a moving object down.

Complete answer:
In the game of carrom board, the surface of a wooden board may have a lot of imperfections on a microscopic scale. Striker slides on the surface of the board to move towards various corners.The motion of the striker is slow because there are a lot of imperfections on the carrom board which causes a large amount of friction which is an unpleasant situation.

So, sprinkling of powder on the surface of the board makes the surface much smoother.Sprinkling of powder makes the surface of the board smoother than before because interlocking between irregularities of the surface is comparatively less. Also the resistance faced by coins is less.

Thus, we conclude that sprinkling of powder on the carrom board reduces friction between the surface of the carrom board, the striker and the coins.

Note: Powder should be sprinkled in the centre of the carrom board and then evenly distributed using striker in circular motion. If few areas are left on the carrom board you can sprinkle some more powder.
