What happen to the force of friction if the surface of contact is polished?

Friction is still there and gravity causes that, if there is no gravity there is no friction. Only in your case friction is reduced because there is less drag because of the polished surface it is not harder to move along the surface. (assuming there is a force moving the object on top of the surface)

What surface has the least amount of friction?
The surfaces used as the measure of lowest friction are generally wet ice on wet ice. Some materials, such as superfluid Helium III have no measurable friction.
Does friction happen in a liquid?
yes
How friction affects motion?
Friction is a very helpful thing and with out it you couldn't move, speed up, slow down, change direction, bend, or twist. Without friction nothing would ever happen. Friction can oppose motion or it can make it difficult for an object to move across a surface. Friction both helps an hinders every thing we do.the object would not move without frictionThe friction acts in the opposite direction to that of direction of motion.So friction slows the object and if no external force is applied the object will come to stop.Friction is a force that opposes the direction of motion between two materials. It is parallel to the surface your object is touching. Friction depends on the coefficient of friction and the normal force (force exerted perpendicular to the surface your object is on; opposes gravity on a flat surface). There are two kinds of friction: static and kinetic. Static friction must be overcome in order to move an object. Once the object is in motion the friction acting on it is called kinetic. Static friction has a threshold of force that is needed to get the object moving but once the object is in motion it can be moved at a constant velocity with less force required.
What will happen to moving objects if there is no friction?
There is no motion
When force is applied to an object but does not cause the object to move?
That will happen if the force applied is less than the limiting value of the friction between the object and the surface that it is in contact with.

Do you have to overcome rolling friction when you slide a bag of groceries across the countertop?
If the bag is sliding across the countertop (i.e., the same surface of the bag is always in contact with the counter), then no. Rolling friction is only relevant when the surface of an object in contact with the surface it moves across always changes.
Why do you not see your reflection when you look at a building made of rough white stone?
Because the surface isn't polished enough to reflect. If it was polished marble or any other polished stone, you might be able to see a reflection. It would be equivalent to getting a reflection from rough concrete, it wont happen. The rough surface of stone or concrete scatters the light reflecting off of it.

The surfaces used as the measure of lowest friction are generally wet ice on wet ice. Some materials, such as superfluid Helium III have no measurable friction.
What would happen if a ramp were coated with a smoother surface the ramps efficiency would?
The answer is : Increase because friction would decrease.
What would always happen when friction takes place?
The velocity of the object will decrease.Heat energy will be generated.Object and surface may get rugged and teared.
What will happen if you apply a force on top of a disk kept on a frictionless surface?
The disc will slow down as a result of the friction applied by the force.
What will happen to friction if the road is wet?
The friction will go down drastically.
When is a mudslide likely to happen?
When the water content of the mud reaches a critical point making its slipperiness overcome the friction coefficient of the supporting surface relevant to its angle.
What would happen if there was more friction?
If friction is more it leads to unwanted things
Does friction happen in a liquid?
yes
