Question

Write the six methods of reducing friction.​

Answer 1

Explanation:

1. Polishing surfaces- It makes the surfaces even and hence reduces friction
2. By streamlining - streamlining reduces the area of contact and thus reduces friction
3. By using lubricants - Friction can be reduced by applying lubricants like oil or grease to the rubbing surface
4. Friction can be reduced by using ball bearing between the moving parts of a machine
5. Friction can be reduced by using wheels to move objects
6. Reduce the contact between the surfaces.

Answer 2

Answer:

1)Friction can be reduced by making the surface smooth by polishing.

1)Friction can be reduced by making the surface smooth by polishing.2)Friction can be reduced by applying lubricants (like oil or grease) to the rubbing surface.
