under damped over damped critically damped vibration proof (part 1)

The video tutorial explains how to derive the equations of motion for overdamped, underdamped, and critically damped systems using a spring-mass-dampener model. It covers the forces acting on the system, the derivation of equations using Newton's law, and the simplification of these equations. The characteristic equation is introduced and solved, leading to an analysis of roots and classification into motion types. Examples of each motion type are provided, along with a definition of Omega D.
