If the two surfaces are moving relative to each other, then the friction between them is Kinetic Friction. Prior to the surfaces moving there was Static Friction between them.

Three types of friction are :1. Kinetic friction :Friction that arises between surfaces in relative motion.2. Static friction :Friction that acts between surfaces at rest with respect to each other3. Rolling friction : Friction that occurs when an object rolls over a surface.3_types_of_friction

kinetic
Kinetic friction is the friction that arises between surfaces in relative motion. Sliding friction is the friction that occurs when an object slides over a surface.
The rougher a surface is, the higher the coefficient of static and kinetic friction will be.
If the two surfaces are moving relative to each other, then the friction between them is Kinetic Friction. Prior to the surfaces moving there was Static Friction between them.
Static
Friction generated between two dry surfaces in contact during motion. Kinetic frictionis a product of the coefficient of kinetic friction and the normal reaction force. It assumes a constant value regardless of the amount of applied force or the speed of the motion. Its value is always less than the limiting friction between the same two surfaces.

Types of friction: 1. Kinetic friction arises between surfaces in relative motion, 2. Static friction acts between surfaces at rest with respect to each other, and 3. Rolling friction occurs when an object rolls over a surface.

Friction; either Static Kinetic [or Rolling]
The coefficient of static or kinetic friction depends on the surfaces that are causing friction. The formula for it is: force of friction over normal force.
