Frequency Amplitude and Period for underdamped motion summary

The video tutorial explains underdamped motion in a spring mass damper system. It introduces the equation of motion, X = a E to the minus Zeta Omega NT times sine Omega DT plus Phi, and describes how the amplitude decays exponentially. The tutorial also defines the damped period (TD) and frequency (FD), providing formulas for these concepts: TD = 1/FD and Omega D = 2π FD.
