Question

how can we decrease friction write five points

Answer 1

There are a number of ways to reduce friction:

1)Make the surfaces smoother. Rough surfaces produce more friction and smooth surfaces reduce friction.
2)Lubrication is another way to make a surface smoother

3)Make the object more streamlined.
4)Reduce the forces acting on the surfaces
5)Reduce the contact between the surfaces.

Answer 2

1,we can decrease friction by using lubricants
2,we can decrease friction by using ball bearings in machines.
3,we can decrease friction by using shoes( under design )
4,we can decrease friction by using water
5, we can decrease friction by using tyres.
