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.

http://pubs.sciepub.com/jmdv/2/1/2/ WebThe natural frequency, as the name implies, is the frequency at which the system resonates. In the example of the mass and beam, the natural frequency is determined by two factors: the amount of mass, and the stiffness of the beam, which acts as a spring. A lower mass and/or a stiffer beam increase the natural frequency (see figure 2). Figure 2.
