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.

Which force is weakened when the floor is wet?
Friction is reduced on a wet floor.
Which force is reduced with the use of lubricant?
Friction
Why do wheel reduce the force of friction?
Wheels reduces the friction because to improve the speed of the machines. friction can be reduced with the help of the lubricants.
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)
Unbalanced force opposing motion between touching surfaces?
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.
Which force is weakened when the floor is wet?
Friction is reduced on a wet floor.
Which force is reduced with the use of lubricant?
Friction
How does friction affect output force?
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.
Why do wheel reduce the force of friction?
Wheels reduces the friction because to improve the speed of the machines. friction can be reduced with the help of the lubricants.
Name the force that exists between the moving parts of a machine and how can this be reduced?
Friction. It can be reduced by lubricating substances such as oil.
What reduced by friction?
efficency is reduced by friction.
Is Friction reduced between polished surfaces?
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
How is friction defined scientifically?
Friction is a force present when things rub against eachother. Friction causes heat energy, and it also causes motion between surfaces to be reduced.
What helped move pyramid stones?
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.
How would the amount of force that is needed to put the load up the inclined plane be reduced?
Reduce the friction
Is it true that rolling friction always reduces the net force acting aginstan objects's motion to zero?
Friction can be reduced, but in most cases there is no practical way to reduce friction to zero.
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)
