In harmonic oscillators it is proportional to speed and causes damping.
In the Frenkel-Kontorova-Tomlinson model, this phenomenon arises from a harmonic chain undergoing stick-slip behavior. In harmonic oscillators it is proportional to speed and causes damping. A body's interface with a fluid often exhibits the skin form of this force, which is independent of area of contact and proportional to the applied load. Converting kinetic energy to heat, it has different coefficients for its static and kinetic types, for 10 points, name this force opposing motion between two objects.
