WebForced oscillations are the converse of free oscillations in which the body can do oscillations independently, for example, free moving pendulum. Moreover, when talking about resonance, it is a frequency of special cases wherein the natural frequency of the body is equal to the driven or forced frequency of the body. WebOn the other hand, the forced oscillation of the mass can be represented by a displacement-time graph. If you've ever analyzed the basic graphs of acceleration-time & displacement-time for SHM, you would have realized that both are 180° out of phase from each other (& so are driver (driver force) and forced oscillations (of mass) from each other).
