by increasing smothness wecan decrease the friction and vice versa
TO REDUCE FRICTION: We can use fine powder on the carrom board to reduce friction
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..
Friction isn't a size. You can increase friction by increasing the pressure on two objects as they pass, or reduce lubrication between them.

yes
1)increasing the roughness of the surface 2)increasing the mass of the object
Examples of SLIDING FRICTION is pushing a heavy rock in your path, or moving a box on the floor.

The fact that you can walk without sliding is an example of friction.
Some examples of relatively high friction surfaces are: sand paper, grass, and asphalt. In general, the rougher the surface, the more friction it has.
