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.
TO REDUCE FRICTION: We can use fine powder on the carrom board to reduce 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.
A lubricant such as oil and ball bearings are just (2) methods of reducing friction.
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.
when i am ask is friction important i say the answer is yes. friction is important and can help people in many different ways. like cars for a example cars use friction to drive on the road. there is many different types of friction to; dry friction, fluid friction, lubricated friction, skin friction, internal friction, ect..... all of these types of frictions can be different a different way.

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.

1) using a lubricant film between moving parts. 2) using low friction materials, such as Teflon.3) reducing surface roughness.
no

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..
Actually, they don't. Are you talking about reducing pollution?
Friction is related to swimming because the water is constantly working against the force of the swimmer and therefore reducing their speed and acceleration. If there was no friction then many of the world's physics would be completely different.
One way to reduce friction is to use a lubricant.
