Answer 1

Q.What are the methods of reducing friction ?

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

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

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

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