Undamped Oscillations: When a Simple harmonic oscillator oscillates with a constant amplitude which does not change with time, its oscillations are undamped S.H.M
Damped Oscillations : When a simple harmonic Oscillator oscillates with a decreasing amplitude with time, its oscillations are called damped S.H.M.
