Hi!
I have a few questions about resonance:
1) What exactly is the "amplitude of driver of oscillation"? And why is the amplitude of the driven object equal to the amplitude of the driver right from the start when the driver frequency is 0?
2) Is the driven system originally oscillating?
3) In reference to the 'light damping' curve, why does the amplitude of driven oscillation increase between 0 and f₀, but decrease after f₀?
4) Also, is a system's natural frequency fixed? eg. No matter how hard I push someone who is sitting on a swing, the amplitude will increase but the frequency will remain constant? How about a brass instrument?
Just started learning this topic so I may have many misconceptions - hopefully a simple basic explanation about the concept of resonance would be good.
