Question

write about different method for reducing friction​

Answer 1

$\huge\mathrm{\pink{Answer}}$

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.

Answer 2

Answer:

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.
