Answer:
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..
- 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
