The sliding friction oscillator is a harmonic oscillator modified, in which besides the elastic force (Felast = -kx) it also acts a sliding kinetic frictional force with the usual shape fk = umg. In practice all mass-spring oscillators are of this type because there is always some friction between the mass and the surface where this slides. Using Newton's 2nd law, we can construct an equation differential for a mass-spring system with friction: F = ma -sgn(v) fk - kx = ma where sgn(v) is the signal function, defined by sgn(v) = 1 V20 V
