If the system is underdamped, it will swing back and forth with decreasing size of the swing until it comes to a stop. Its amplitude will decrease exponentially.
Important Points
Overdamped System: ζ > 1
This is the equation of aperiodic motion i.e. the system cannot vibrate due to over-damping. The magnitude of the resultant displacement approaches zero with time.
Underdamped: ζ < 1
This resultant motion is oscillatory with decreasing amplitudes having a frequency of ωd. Ultimately, the motion dies down with time.
Critical Damping: ζ = 1
The displacement will be approaching to zero with shortest possible time.
