Question

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

Answer 1

Answer:

What are the methods of reducing friction ? Explain

1) By using lubricants: friction increases as the roughness of the surface increases. ...

2) Polishing surfaces: It makes the surfaces even and hence reduces friction.

3) By using ball bearings: Rotating machines can be mounted on ball bearings. ...

4) By streamlining: streamlining reduces the area of contact and thus reduces friction.
