Answer: oil,grease
Explanation: friction in machines is usually reduced by lubrication. Oil and grease are commonly used lubricants. Oil and grease is applied between the moving parts of machines. This fills the fine pores depression in the surfaces and thus reduces friction. Sometimes, we use solid lubricants in the form of powders. We spread fine powder on carom board to reduce friction between the coins on the board
