Question

what are the way used to reduce friction?describes

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

Answer:

1) polishing

2) applying oil or grease

3) ball bearings

4) lubricants

these are few ways to reduce friction . polishing makes the surface smooth and thus friction decreases . applying oil or grease reduce friction between surfaces and with ball bearings friction between friction between rolled object and surface can be reduced.
