Parametric Oscillation
Energy can be pumped into oscillations by changing system properties, not just by pushing

Why must the parameter variation frequency in a parametric oscillator often be twice the natural frequency of the oscillator?
Because the oscillator cannot respond to any other frequency due to damping effects.
Because this frequency relationship allows energy to be efficiently transferred into the oscillations through parameter modulation.
Because the parameter variation directly pushes the oscillator at its natural frequency.
