because it does
Since the frictional force is directly proportional to the normal reaction When two surfaces are pressed harder normal reaction increases .'. Friction increases
Frictional force is the force that opposes motion between two surfaces.
There are basically two ways to increase friction between two surfaces, which are, make them rougher (increased co-efficient of friction) or press them together with greater pressure. In either case, you are increasing the interaction between irregularities on the surfaces. Completely smooth surfaces would, in theory, be frictionless.
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.
As they come into contact so tight friction would increase As roughness increases frictional force too increases.

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

velocity and texture
Frictional force is the force that opposes motion between two surfaces.
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 .
