WebThe phase-space diagram for a damped oscillator also shows that the oscillator is losing energy. As the amplitudes of the velocity and position decrease, the phase diagram spirals inwards. In classical mechanics, this is described as an "attractor" and shows that the system is trapped in a potential well from which it cannot escape.
