Dynamics and Vibrations: Notes: Free Undamped Vibrations …

5.2 Free vibration of conservative, single degree of freedom, linear systems. First, we will explain what is meant by the title of this section. Recall that a system is conservative if energy is conserved, i.e. potential energy + kinetic energy = constant during motion. Free vibration means that no time varying external forces act on the system.
