 Math Emeritus Sci Advisor Thanks PF Gold P: 39,565 Mathematically the differential equation mx"+ cx+ kx= f(t) gives an "oscillatory" solution as long as the discriminant c2- 4mk< 0. A "damped" oscillation is one in which c> 0. A "forced" oscillation is one in which f(t) is not identically 0. No, in that sense, "damped" and "forced" are completely independent.
