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..
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.
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.
by reducing the mass you reduce the friction, and by reducing the friction reduce the fuel needed to move the car, this applies to all cars not only CO2 cars.

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

smooth the surfaces lubricate the surfacesfor gears, the shape of the tooth is importantselect the materials, some combinations of materials have lower friction than others.for something rolling, use ball bearings, air cushion or roller bearingIncrease friction:roughen the surfaces.remove lubricantselect the materials, some combinations of materials have lower friction than others.
1) using a lubricant film between moving parts. 2) using low friction materials, such as Teflon.3) reducing surface roughness.

no
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 mass you reduce the friction, and by reducing the friction reduce the fuel needed to move the car, this applies to all cars not only CO2 cars.
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.
by increasing smothness wecan decrease the friction and vice versa
