With damping: |
The animated gif at right (click here for mpg movie) shows two 1-DOF mass-spring systems initially at rest, but displaced from equilibrium by x=xmax . The black mass is undamped and the blue mass is damped (underdamped). After being released from rest the undamped (black) mass exhibits simple harmonic motion while the damped (blue) mass exhibits an oscillatory motion which decays with time.
