2nd Order ODE: Derive Equations, explain parameters, draw block diagram!

undamped natural frequency = describes the frequency at which the system oscillates in the absence of any external damping or driving forces.

damping ration = The damping ratio is a parameter that describes the amount of damping in a second-order system. It is denoted by the symbol ζ (pronounced "zeta") and is defined as the ratio of the actual damping coefficient to the critical damping coefficient for the system.
