Question

Discuss the method of reducing friction with example ?

Answer 1

Answer:

_By using ball bearings: Rotating machines can be mounted on ball bearings. Rolling friction is lesser than sliding friction

_by streamlining: streamlining reduces the area of contact and thus reduces friction

Explanation:

Answer 2

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.
