Question

Write different methods to reduce friction

Answer 1

Answer:

by making surface smooth by polishing

by applying lubricants

by using ball bearing between two moving parts in machine

are three ways to reduce friction

Answer 2

Answer:

Some methods to reduce friction are:-

• 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.
