What can reduce friction?

Answer 1

Lubricants

We 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 wheels

Rollers 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 surfaces

2. Adding lubricants

3. increasing the temperature

4. wetting the surface

5. removing impurities, etc. :)
one way to reduce friction is by using oil or grease this makes it smoother and reduces friction
nothing prtroleum
If you put something on wheels it reduces friction. Also if you lubricate a surface the friction will also be reduced.
this i dont know
You 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.

1. Grease the interfacing surfaces
2. Change to two materials with lower coefficients of friction
3. Insert rollers between the two surfaces to change the type of friction involved
4. Change the applied forces so they tend to point in the same direction (reduce the normal force)

ANSWER IT

In which of the following situations or places would you want to reduce the force of friction? A.You are sitting on a park bench.B.You drive your boat through waves.C.Your bedroom door squeaks when you open or close it.D.You are running around a track.

THE ANSWER IS B&C ------- APEX (:
it ca be reduce by oil
1. using grease or any other lubricant 2. using smoother surfaces 3. using fluids of lower viscosity (measure of resistance to flow) 4.Use rollers, wheels or ball bearings and 5.Objects like cars and planes are modelled with streamlined shapes.
Lubricate or reduce contact between moving parts (e.g. magnetic levitation).
By checking your vehichle daily

1. Ball bearing
2. Stream lining
3. Polishing
4. Lubricating

increase its aerodynamics, using lubrication, super-cavitation(if its underwater)
The way to reduce friction, is by applying the same force to the same dirrection that gravity is pulling.
oil

grease

sand
Don't really know five off the top of my head, but some easy ones are lubricant, soap, polish, and wax, most of these will fill the tiny holes on the surface and make it more smooth.

Hope this helps!

_To reduce friction by making the surface smooth..

1> add some lubricant in between the surfaces .

2> smoothen the surfaces to a limit .if u smoothen it more then friction will increase .
You can reduce friction in a mechanical system by using a lubricant, or by polishing the surfaces that come into contact.
As rolling friction is comparatively very low we use ball bearings. Best lubricants could be used to reduce the friction to a greater extent.
The following methods are used to reduce friction

• the 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 surface
lubricants and Ball bearings
Oil or stuff with a surface.
It is reduced by using oil or grease in between them
Smooth 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!)

Answer 2

Using lubricants such as oil or grease, polishing surfaces to make them smoother, and using ball bearings or rollers can help reduce friction between surfaces. Additionally, reducing the load or pressure on the surfaces in contact can also minimize friction.

Answer 3

You can reduce friction in a mechanical system by using a lubricant, or by polishing the surfaces that come into contact.
