Abstract
The fundamental principle in Physics is that the energy in the Universe is conserved; it can change in form but cannot be created or destroyed. Energy can be in various forms, important of these forms for vibration and rotor dynamics study is kinetic energy and potential energy (strain energy). In freely vibrating systems, these energies keep continuously change in these forms thus producing oscillatory motion for the mass.
