Increase the total area of direct contact between the two materials and decrease minute deviations from direct contact of the materials, also use a superconductor as a "mortar." Additionally ensure the two materials are of different conductivity. Additional mass may be used to add to the gravitational force pressing down on the surfaces once they make contact. Additional friction can be achieved by the use of force on the lower surface only, allowing the upper surface to remain static.

1. Roughen the contact surfaces (increasing the surfaces areas),
2. Dry the contact surfaces,
3. Use softer materials,
4. Eliminate all loose materials between the contact surfaces,
5. Increase the weight of the moving body,
6. Apply a sticky substance to contact surfaces,
7. Remove all lubricating substances from the contact surfaces.
8. Adding Weight to object (sand boxes in cars for icy roads)

How could you reduce the friction between 2 surfaces?
One way is to put rubber bands on both of the surfaces
Why do slippery liquids reduce friction?
Friction is phenomenon you see between two rough surfaces. A slippery liquid or lubricants when applied, coats over these rough surfaces creating a layer of the lubricant itself. Liquids like lubricants has very low viscosity, that is the sliding friction between two liquid layers, hence they easily slip over each other. In this way they help 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.
Explain how friction reduces the efficiency of machines?
one way to reduce friction between two surfaces is to add oil. oil fills in the gaps between surfaces , and keeps many of the high spots from making contact. because there are fewer contact points between the surfaces, the force of friction is reduced. more of the input work then is converted to output work by the machine.
What is one way that you could reduce friction between two surface?
We can decrease friction by lubrication - that is to say, we put in some slippery substance, usually oil - or by separating the two surfaces with something that rolls, ball bearings or wheels of some kind.

What is one way you could reduce friction between two surfaces?
By applying lubrication e.g greasingOne way is that if rough surfaces produce greater friction than smooth surfaces. Friction also increases if the surfaces push hard against each other.separate the two surfaceLubrication can be used and the surfaces should also be less bumpy or ragged and be able to easily slide over each other.

What are the main factors on which friction depends?
the amount of friction depends on the type of surfaces that are rubbing against each other. when surfaces are smooth, they move against each other more easily. friction is greater between rough surfaces. in order to reduce friction in the moving parts of machines, scientists and engineers use oil and other lubricants. these lubricants make the surface smoother.
Why does oiling and lubricating reduce friction?
no substance is perfectly smooth.it has tiny bumps and bruises and when two surfaces move over each other the bumps and holes in get in each other's way.oil covers up these bumps.it also forms a layer between the two surfaces and prevents direct contact between them.there is very little direct contact between the holes and this way the friction is reduced
What is one way to overcome friction in a machine?
use lubricants it smoothens the surface and reduces the irregularity between both the surfaces resulting in reduction of friction
What can reduce friction?
LubricantsWe can apply lubricants like oil or grease on the moving part of a machine to reduce friction. With less friction, machines can last longer.Rollers and wheelsRollers and wheels reduce friction between the surfaces of objects and the floor. This enables us to move heavy objects with ease.Smoothing and lubrication.there are various methods to reduce friction, like:1. Polishing the surfaces2. Adding lubricants3. increasing the temperature4. wetting the surface5. removing impurities, etc. :)one way to reduce friction is by using oil or grease this makes it smoother and reduces frictionnothing prtroleumIf you put something on wheels it reduces friction. Also if you lubricate a surface the friction will also be reduced.this i dont knowYou can reduce friction by:Adding oil Friction can be reduced by using smooth surfaces, or by lubrication. Things like oil or grease are lubricants, and help things to move past each other easily. You can reduce friction by putting the object on wheels. Also, in machines, you could oil the parts.Grease the interfacing surfacesChange to two materials with lower coefficients of frictionInsert rollers between the two surfaces to change the type of friction involvedChange the applied forces so they tend to point in the same direction (reduce the normal force)ANSWER ITIn which of the following situations or places would you want to reduce the force of friction?

Best lubricants could be used to reduce the friction to a greater extent.The following methods are used to reduce frictionthe parts which slide against each other are highly polished.as friction of liquids is less than that of solids,therefore oil or grease is applied between the parts of machinery.sliding friction is converted into rolling friction by use of ball bearings.There are many ways of reducing friction , one of them is lubricating the surfacelubricants and Ball bearingsOil or stuff with a surface.It is reduced by using oil or grease in between themSmooth surfaces and lubrication decrease friction. Appropriate values for the surface energies of the parts reduce friction (for example Teflon and steel)(note that if the surfaces are VERY smooth (we are talking about optical smoothness now) there will be no room for air or lubricants between the surfaces and they can become very difficult to separate!)
A way to reduce friction?
Smoothen the surface that's causing the friction. :)
