Question

how can you minimise friction between two surfaces mention three ways

Answer 1

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

You can minimise the effect of friction by--
1)using lubricants ( ex--greese)
2)by converting siding friction into rolling friction due to the use of ball bearings.
3)By using streamlined bodies.
