friction is a necessary evil for the man-kind although it has many advantages it also carries any dis-advantages with it which are discussed below :-.
1. it reduces the efficiency of any machine, as some of the energy is lost due to friction as heat energy.So the energy reaching the output would be {input energy - frictional energy}
2. it causes wear and tear of machines.
3. produces unnecessary heat.

What is friction reduction?
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.
Which force is weakened when the floor is wet?
Friction is reduced on a wet floor.
How do skiers reduce friction?
Friction between skis and snow may be reduced by waxing the skis. Air friction is reduced by tucking the body into a streamlined position.
Is Friction reduced between polished surfaces?
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
How is friction reduced in a motor?
by lubricating it by grease
How air friction is reduced in cars?
With aerodynamics.
How can be friction reduced?
stop it yourself
Which force is reduced with the use of lubricant?
Friction
What effect does friction have on a machines efficiency?
Efficiency of the machine is reduced due to loss of energy by friction.
What are two means by which friction may be reduced?
Lubrication and ball bearings both reduce friction.
