查看完整版本 : Resonance and damping （九龍巴士企業之歌-共創佳績）

SHM is a kind of free oscillation 

It has a natural frequency, and you drive it and is forced

Driving close to natural, it is called resonance

The amplitude is very large and it is super noisy

A damped oscillation may be drag acting on pendulum 

And there is loss in energy and amplitude reduces over (over by time)

It reduces resonant vibrations such as a clock with minimum damping

For those systems which we want oscillation stop fast, we need critical damping

But if overdamping is too much, it will take a long back to equilibrium 

Remember calculation of SHM graph, you can only see change in amplitude
