Question

write two method to avoid friction​

Answer 1

Polishing and greasing .

Answer 2

hey buddy this is your answer

the methods to avoid friction are:

(i) By using lubricants: friction increases as the roughness of the surface increases

(Ii)Polishing surfaces: It makes the surfaces even and hence reduces friction

(iii)By using ball bearings: Rotating machines can be mounted on ball bearings

(iv)By streamlining: streamlining reduces the area of contact and thus reduces friction.
