Relative velocity is the velocity of an object as observed from a particular reference frame, and it varies with the choice of reference frame.

What is the force that resists motion between two surfaces?

http://hyperphysics.phy-astr.gsu.edu/hbase/frict.html WebThe resistive force between solid surfaces in contact that resists their relative tangential motion. "Friction" is often synonymous with "dry friction". The resistive force between surfaces in relative motion through a fluid (liquids & gases). Air resistance or aerodynamic drag is a type of viscous friction. rota ferro new world

"WebKinetic friction is a force by a surface parallel to the surface that opposes the motion of a sliding object and causes it to slow down. When the friction prevents the object from sliding, it is called static friction. Rolling resistance impedes the rolling of a wheel. Drag opposes and slows the motion of an object through a fluid (see Figure 4 ... " - Surface resistance to relative motion
