Yes friction can be reduced.Merely by using a surface type which is much smoother.Therefore the friction will be largely reduced.However it can never be diminished as it will be ever present.
It means what how can the friction be reduced. To answer this question, Friction can be reduced by devices like ball bearings, wheels and lubricants.
Friction is reduced on a wet floor.
Friction between skis and snow may be reduced by waxing the skis. Air friction is reduced by tucking the body into a streamlined position.
stop it yourself
by lubricating it by grease
efficency is reduced by friction.

when we polish surfaces, the molecules or atoms of surface come closer to each other so there is no space for fiction so it is reduced but not reduced to zerowe cant reduce friction to zeroWhen we polish a rough surface smoothly,the unequalities gets reduced,therefore friction is reduced
by lubricating it by grease
no not really
With aerodynamics.
stop it yourself
Friction
Efficiency of the machine is reduced due to loss of energy by friction.
Lubrication and ball bearings both reduce friction.
