friction is the force which opposes relative motion between the bodies.All the surfaces are not perfectly smooth,there will be some irregularities in its surface,when other bodies rub on this surfaces it will stucj in these irregular spaces this is called friction,there is allot of definitions about friction,but this theory is universly accepted,there are twko types of friction
1)static friction:its the friction when two bodies are at rest
2)kinetic friction:when two bodies are in motion
when rubbing kinetic friction is acting

Frictional force is the force that opposes motion between two surfaces.
The force that opposes relative motion btwn two surfaces in contact with each other
FrictionWhen two surfaces touch each other, there is some adhesion between the two. That adhesion results in friction, which opposes the motion of one surface with respect to the other.Friction opposes motion between two surfaces.*you will have more friction if you have rougher surfaces. the smoother the surfaces, the less friction.**friction is caused by the microscopic hills and valleys on objects rubbing up*
the force that opposes the motion of two touching surfaces is velocity.
the force that opposes the motion of two touching surfaces is velocity.
