Want this question answered?
by increasing smothness wecan decrease the friction and vice versa
friction has many advantages walking,moving of a vehicle etc...............
friction helps us to move
TO REDUCE FRICTION: We can use fine powder on the carrom board to reduce friction
A necessary evil means that friction has advantages as well as disadvantages so it called as necessary evil. Advantages of friction areits helps us to walkto writedriving car, etc,

oiling a squeaky door
yes
1)increasing the roughness of the surface 2)increasing the mass of the object
When friction increases, the object slows down. It can be used in, f. ex, brakes.
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..
