WebAug 16, 2024 · Resonance can only occur when a system has some form of inertia as well as a restoring effect. This means a physical mass must provide inertia. The restoring effect is any kind of force that acts to bring this mass back into an equilibrium position. The specific combination of inertia and a restoring force produces a natural frequency.
