How can you reduce friction between two surfaces?

Answer 1

1) using a lubricant film between moving parts.

2) using low friction materials, such as Teflon.

3) reducing surface roughness.

Answer 2

We can reduce friction by putting oil , banana wrappers, lubricants, air bags (in some machines, lubricants and such things are not allowed to use, there we use air bags in between two object), polishing, rollers or ball bearings, usings fluids of low velocity, streamline structure in cars, planes, etc., increasing the temperature, wetting the surface, removing impurities, super cavitation (if under water), etc.....

Answer 3

You can polish the surfaces. That will reduce the friction.
Have a smoother surface, or have lubricant that can cover all bumps.
lubricate them
You could lubricate them or smooth them.

A lubricant is anything that reduces friction between two objects. Examples of lubricant are oil, soap, water, wax etc.

When an object is at rest on a particular surface, the frictional force keeping it from sliding in any given direction is known as static friction; the magnitude of this force is always less than or equal to the product of those surfaces' static friction coefficient and the component of the gravitational force (weight) of the object perpendicular to the plane of the surface, the latter of which is equal to the normal force that is exerted by the intermolecular bonds in the surface material, upward and perpendicular to the plane of the surface itself. (In other words, Fs ≤ µsFn, where Fs=force of static friction, µs=static friction coefficient, Fn=normal force of surface upon object.)
Add oil
the answer is have a smother surface to prevent bumps. this will stop the car from producing friction

We can decrease friction by applying lubricant between two surfaces or by smoothening the two surfaces.
Lubrication, reduce pressure on the surfaces, generally introduce separation between the surfaces.

Answer 4

Less pressure / weight.

Or a different material. F.ex. use som liquid to grease the two elements and lessen friction.

Answer 5

• By applying kinetic friction or moving the opposite direction.
• Reduce friction of the surface
• Reduce friction of the wheel, tire, etc.

Answer 6

To reduce the friction you can:

-add lubricants to the surfaces

-make the surfaces smoother

-make the surface softer
