Relative motion is the concept that the motion of all objects is relative to other objects. If you are sitting still right now you are not moving relative to the earth, however you are moving relative to sun.
Relative motion
By the relative motion of neighbour objects

A change in an objects position relative to a reference point is called motion.
A change in an objects position relative to a reference point is called motion.
Friction
Friction wasn't invented, it is an interaction between objects : "Friction is the force resisting the relative lateral motion of two solid surfaces in contact, or a solid surface in contact with a fluid"
Relative motion is : The comparison of motion between two different objects from the view of another object
The force that resists motion between objects that are in contact is called friction. One object can be stationary or they both can move.
