Its reduce by following ways
By polishing the surface
use lubricants
by streamlining
by air cushion
by converting sliding friction in to rolling friction
By making the surface rough for increasing friction....... use any lubricating material to reduce the friction.. use rollers to decrease the friction force.. make less contact between 2 connecting materials..
Apply a larger force. Make the object less massive. Decrease air resistance acting on the object. Decrease the coefficients of friction by using a 'smooth' surface, where friction is negligible.
it can give us warmth
You can describes the friction
Friction will decrease if the coefficient of friction decreases. This can be caused by having a smother surface up to a point. (When two surface are TOO smooth the friction actually increases due to molecular attraction.)
oil, graphite, grease
use lubricants like grease and oil...

Decrease friction .

1) using a lubricant film between moving parts. 2) using low friction materials, such as Teflon.3) reducing surface roughness.
Friction is decreased by means of lubrication.
Polish the interacting surfaces or decrease the normal force acting on the moving object.
Three ways to decrease the force of friction are- 1.)Polishing 2.)Lubrication 3.)Ball Bearings
Decrease friction.
