The factor that affect friction is depends solely on the smoothness of the surface in contact. The force needed to move the two surfaces to the pass with one another is easier if they are smooth.
The two factors on which friction depends are as follows 1. Area of contact 2. Mass of object
Friction= Normal force* Coefficient of friction
pressure differences, coriolis effect, friction
My textbook says speed between two surfaces does not affect friction.
The two factors are the coeffiecient of friction, and the 'normal' force, which is equal and opposite to the weight of the object. The coefficient of friction is diffeerent for different objects. Friction force = Coeff. X Normal Force
Friction= Normal force* Coefficient of friction

Two factors that determine the strength of friction between two objects is the smoothness of the surfaces in contact, and the weight of the object moving horizontally.
The strength of the force of friction depends on two factors: the types of surfaces involved and how hard the surfaces push together.
The force of friction between two objects is the product of the normal force and the coefficient of friction. The normal force is the component of force that is perpendicular to the plane of friction. For example, if you are pushing on a block of wood on the floor with a force F at an angle of 30 degrees above the horizontal, then the normal force N = F sin 30. The coefficient of friction is specific to the two materials, in this example the block of wood and the floor. In addition, there is a static coefficient of friction (applicable to a stationary situation) and a kinetic coefficient of friction (applicable when the object is already moving).
