Resonance dynamics
Resonance describes the phenomenon of increased amplitude that occurs when the frequency of an applied periodic force (or a Fourier component of it) is equal or close to a natural frequency of the system on which it acts. When an oscillating force is applied at a resonant frequency of a dynamic system, the system … See more Resonance occurs when a system is able to store and easily transfer energy between two or more different storage modes (such as kinetic energy and potential energy in the case of a simple pendulum). … See more Resonance manifests itself in many linear and nonlinear systems as oscillations around an equilibrium point. When the system is driven by … See more Mechanical and acoustic Mechanical resonance is the tendency of a mechanical system to absorb more energy when the frequency of its oscillations matches the system's natural frequency of vibration than it does at other frequencies. It may cause violent … See more The Q factor or quality factor is a dimensionless parameter that describes how under-damped an oscillator or resonator is, and … See more A familiar example is a playground swing, which acts as a pendulum.
