First one is normal, second never stops, third one is self-powered and
will become unstable after a little bit. conclusion= damping is how much
the spring wants to oscillate.
You said: " conclusion= damping is how much
the spring wants to oscillate." Well, that's not true. In fact, it's just the opposite. Dampening reduces the amount of oscillation in a system by dissipating some of the energy and converting that energy into heat. A real world example of a dampener is a shock-absorber on a car.
