how hard the surfaces push to gether the types of surfaces involved
According to scientists, there are two factors that affect the friction force between two surfaces which are the types of surfaces involved and how hard the surfaces push together.
Frictional force is the force that opposes motion between two surfaces.
Nothing on the list included with the question describes that force.
we can reduce it by providing lubrication means using oil between 2 surfaces as lubricant.

1. The Coefficient of friction between the two surfaces. 2. The force applied bringing the two surfaces together.
Frictional force is the force that opposes motion between two surfaces.
The magnitude of the frictional force is directly proprotional to the normal reaction between the two surfaces.(2)Magnitude of the frictional force is independent of shape and area of the surfaces
Nothing on the list included with the question describes that force.

Yes the application of a load normal to the plane of the smooth flat surfaces will increase the friction between the surfaces.
1. The Coefficient of friction between the two surfaces. 2. The force applied bringing the two surfaces together.
maybe it could be something related to the universe
1 . By polishing the surfaces in contact 2 . By lubricating the surfaces in contact with oil or grease .
As they come into contact so tight friction would increase As roughness increases frictional force too increases.
