Webb3 dec. 2024 · Updated on December 03, 2024. Natural frequency is the rate at which an object vibrates when it is disturbed (e.g. plucked, strummed, or hit). A vibrating object … WebbThe natural frequency is the frequency at which the system would oscillate if it were given an initial displacement and then allowed to vibrate freely. The period T is the inverse of the natural frequency. (1.6) Furthermore, the damping coefficient divided by mass can be represented as (1.7) The corresponding amplification factor is (1.8)
