Friction can be caused by many things, but generally it is the result of rough surfaces touching other rough surfaces.
We calculate the force of friction on an object by multiplying the coefficient of friction for that object AND THE SURFACE IT'S TOUCHING (µ) by the force of gravity acting upon the object (if the object is on a flat surface--if not, you take the component of gravity perpendicular to the surface the object is resting on)--that is, the object's weight.
In order to reduce µ efficiently, one could try to lubricate the object, or to sand down any wood surfaces, etc. to make both sides as smooth as possible.
Static friction is generally harder to overcome compared to kinetic friction because static friction is the force that resists the initial motion of an object. Once an object is in motion, the friction force is reduced to the kinetic friction force, which is usually lower.
Friction is the force that is reduced when using a lubricant. Lubricants help to decrease the resistance between surfaces in contact, making it easier for them to slide past each other.
Friction increases with factors like surface roughness, applied force, and contact area. It decreases with factors like lubrication, smooth surfaces, and reduced contact force.
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)
The unbalanced force that opposes motion between touching surfaces is called friction. It acts in the opposite direction of the applied force and depends on the nature of the surfaces and the force pressing them together. Friction can be reduced by using lubricants or by increasing the smoothness of the surfaces.
Simply put, friction reduces output force. The more friction there is, the less effectively power will be delivered, and this results in reduced output force.

Friction. It can be reduced by lubricating substances such as oil.
efficency is reduced by friction.
when we polish surfaces, the molecules or atoms of surface come closer to each other so there is no space for fiction so it is reduced but not reduced to zerowe cant reduce friction to zeroWhen we polish a rough surface smoothly,the unequalities gets reduced,therefore friction is reduced
Friction is a force present when things rub against eachother. Friction causes heat energy, and it also causes motion between surfaces to be reduced.
The inclined plane in the form of a ramp. A sledge with narrow runners which reduced friction. Friction was further reduced by pouring a lubricant such as water or oil under the runners. The motive force was the brute force of thousands of naked slave labourers.

Reduce the friction
Friction can be reduced, but in most cases there is no practical way to reduce friction to zero.
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.
