describe any three ways to increase and reduce friction
Answers
Answer:
lubricants ,ball bearing and polishing reduce friction.by applying more force to object,by increasing mass of the object, by creating rougher point of contact increases fiction
Answer:
Methods for decreasing friction:
Make the surfaces smoother. Rough surfaces produce more friction and smooth surfaces reduce friction.
Lubrication is another way to make a surface smoother. ...
Make the object more streamlined. ...
Reduce the forces acting on the surfaces. ...
Reduce the contact between the surfaces.
What are the methods of reducing friction ? Explain
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.
