Question

mention any three ways of minimising friction ????????​

Answer 1

Answer:

By polishing the surface, as polishing makes the surface smooth and friction can be reduced. Using lubricants such as oil or grease can reduce the friction between the surfaces. When objects are rolled over the surface, the friction between the rolled object and surface can be reduced by using ball bearings.

Answer 2

Explanation:

The three major ways in which friction can be reduced are:

making the surface of contact smooth.

attaching ball bearings if they are machine parts or by adding lubricants such as grease.

by making the motion of objects to be rolling than in sliding motion.
