→The result of smoothening is that friction between the striker and the board decreases and striker slides smoothly on the surface, not losing its momentum too quickly. Hence, we can say that sprinkling of powder on the carrom board reduces friction and makes sliding smoother and easier.
→The friction between the boat and the beach (sand) is much greater than that between the boat and the sea. That is why it is more difficult to pull a boat on the beach than on the sea.
