Question

Write different methods of increasing and reducing friction.​

Answer 1

Answer:

here is your answer hope it helps ☺️

Explanation:

° Use of lubricants: In machines, friction can be reduced by applying lubricants between the contact surfaces to fill the fine pores or depressions in the surfaces and make them smooth thereby reducing friction.

° Polishing : unevenness of the surfaces can be reduced by polishing, thereby reducing the friction
