Friction on a moving body is dependent on two basic factors and it can be represented as follows
Friction force = (Coefficient of friction between the moving surfaces)*( Normal Force between the surfaces)
Reducing any or both of the two factors reduce friction.
Coefficient of friction can be reduced by:
1. Making the surfaces smoother.(effective for moving bodies in gas,liquid, or on solid/semisolid surfaces)
2. Applying 'Lubricant'. (effective for bodies moving on solid/semisolid surfaces)
The normal force can be reduced for bodies in gas and liquids by reducing the press of the medium. (Hence vacuum and high altitude offer less friction than sea level for space crafts). Reduction of the normal force between solid bodies is not practical for machines since this will entirely alter their usefulness. But of course friction couplings, brakes etc use variation of normal force as main criteria for their operation.

Does sand reduce friction?
No, sand does not reduce friction but increase friction.
How can you reduce and increase friction?
Lubrication to reduce friction. To increase friction step on the brakes.
What are the ways of increasing and reducing friction?
TO REDUCE FRICTION: We can use fine powder on the carrom board to reduce friction
What kinds of substance reduce friction?
Friction is the act of one surface rubbing against another. To reduce friction, use something that offers a small amount of friction. Smoother substances reduce friction. A way to reduce friction is to use something which offers a small amount of friction. For example, you could use something like plastic or glass. Water, most liquids and different types of oil reduce friction. Powder, oil and grease are used in between surfaces to also reduce friction.
How do you reduce the friction and vice versa?
Reduce the friction . . .Apply lubricant to the surfaces in contact, or reduce the mutual pressure.Friction the reduce . . .The phrase has no physical significance.
How can you reduce the effect of friction on the motion of a body?
by applying water on the floor.
What is done to reduce friction in ski jumping?
apply wax to the bottom of your skis
Does sand reduce friction?
No, sand does not reduce friction but increase friction.
How can you reduce and increase friction?
Lubrication to reduce friction. To increase friction step on the brakes.
Do wheels reduce friction?
yes because when they brake the friction is caused to reduce
What are the ways of increasing and reducing friction?
TO REDUCE FRICTION: We can use fine powder on the carrom board to reduce friction
What kind of friction can help reduce friction?
I never heard of friction reducing friction. You can reduce friction by using lubricants, as well as using wheels (as in ball bearings).
How does oil reduce air friction?
Oil is mainly used to reduce friction between contacting surface, e.g., metal on metal - not to reduce air friction.
What are the factors that reduce in case of friction?
the factors that reduce in case of friction are the velocity and acceleration.
What does a bit of oil reduce in science?
Oil is used to reduce friction.
What kinds of substance reduce friction?

What are the ways in which friction is reduce on aeroplane?
by giving it better aerodynamics you can reduce friction. but also the faster it goes the more friction it gets.
