Friction can be increased by reducing the speed of the moving object. Friction can also be increased by increasing the weight of the moving object.
One way to increase friction is to increase the weight of the moving body. Another way is to increase the roughness of one or more of the surfaces.
TO REDUCE FRICTION: We can use fine powder on the carrom board to reduce 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..
by increasing smothness wecan decrease the friction and vice versa
There are a few ways to reduce friction. For example one can apply water or oil to the surfaces that are rubbing together.

1)increasing the roughness of the surface 2)increasing the mass of the object

For example-the free wheel of a cycle, the axle of a motorcar.

Use a surface that has a higher coefficient of static/kinetic friction and/or add more force downwards on the object.
There are many ways in which you can show increasing opportunity cost on a graph. You could show it in comparison to satisfaction for example.

friction is caused by the irregularities in surfaces.less the irregularites, more the smoothness.so therefore to increase friction the best way is to make the surface rough.by doing so there will be a resistance against te direction of force.
