AI Thread Summary
The Q factor of a bowl of water at resonance is influenced by the mode being excited, with the lowest mode yielding the highest Q factor. Surface waves are a key consideration in this context. The realistic Q factor can range from ten to twenty cycles of visible motion, depending on the bowl's depth and dimensions. Factors such as the source's position and the physical characteristics of the water also play a significant role. Understanding these dynamics is essential for accurately determining the Q factor in practical applications.

What Q factor can be realystically achieved by a bowl of water at resonance? Source presumed in the centre.

Are you referring to surface waves of the water?
It would depend on what mode you are exciting. The highest Q factor would be for the lowest possible mode - water sloshing from side to side could make ten to twenty cycles of visible motion but it would depend upon the depth and all the other dimensions.
 

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
