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..
IT can move or kiss or bold
TO REDUCE FRICTION: We can use fine powder on the carrom board to reduce friction
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.
A lubricant such as oil and ball bearings are just (2) methods of reducing friction.
Its reduce by following ways By polishing the surface use lubricants by streamlining by air cushion by converting sliding friction in to rolling friction
it can give us warmth

Polishing the surface or coating it with a lubricant is a way of reducing friction. To increase friction just hammer some ridges on the surface.
1) using a lubricant film between moving parts. 2) using low friction materials, such as Teflon.3) reducing surface roughness.
It depends on what you are referring to. Generally some ways of reducing friction are by using smoother surfaces, using fluids with lower viscosities, using grease or any lubricant, using rollers/wheels, using ball bearings, and with objects like cars and planes- these are usually made with streamlined shapes.
By reducing the contact surface area of the object and by applying the lubricant between the two contact surfaces lassens or minimizes the effect of friction.
Friction can be maximized or minimized in several ways depending on the material, device construction and purpose, for example:Minimizing friction of a circling axis can be made by bearings, which usually have rolling balls. Rolling has usually less friction than sliding.In slide systems, friction can be minimized in various ways such as:Polishing the surface of both sliding sides (the opposite will increase friction)Adding a liquid such as oil between them. Oil fills the micro gaps on the surfaces therefore creating a slippery surfaceUsing certain techniques, e.g. air insulation, magnetic insulation
