A lubricant such as oil, grease, graphite powder or PTFE can reduce the friction between two surfaces. Or using metal balls to space them and reduce the contact surface area as used in ball bearings.
The coefficient of static friction between two surfaces is 0.60.
The two forms of friction between two sliding surfaces are static friction, which occurs when the surfaces are at rest relative to each other, and kinetic friction, which occurs when the surfaces are in motion relative to each other.
Friction is the force that acts between two surfaces in contact. It resists the relative motion or tendency of motion between the surfaces.
An example of harmful friction is when two metal surfaces rub together, causing wear and tear. This can be reduced by using lubricants like oil or grease to create a barrier between the surfaces, reducing the direct contact and minimizing friction.
The maximum static friction that can be exerted between two surfaces in contact is equal to the coefficient of static friction multiplied by the normal force between the 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

Net force is the sticking point between two surfaces that cause friction.
Static
The friction between two flat surfaces can be divided into static friction, which occurs when the surfaces are at rest relative to each other, and kinetic friction, which occurs when the surfaces are in motion relative to each other. Static friction is generally greater than kinetic friction.
The level of friction between two surfaces is influenced by factors such as the roughness of the surfaces, the force pressing the surfaces together, and the type of material the surfaces are made of.
The friction felt between two flat surfaces can either be sliding friction or static friction.
