Newton's Law of Cooling and Resonance Phenomena

AI Thread Summary
The discussion focuses on determining the natural frequency of water molecules using Newton's law of cooling and resonance phenomena. The natural frequency refers to the frequency at which a system oscillates without external forces. Calculating this for a single water molecule at 25 °C and 1 atm is complex, as it typically requires quantum chemistry methods or simplified models. The conversation highlights that discussing a single molecule in this context may not be meaningful. Ultimately, the approach to finding vibrational frequencies must consider the limitations of molecular behavior under specified conditions.

Can we find the natural frequency of water's molecules by using of Newton's law of cooling and resonance phenomena?
 
Physics news on Phys.org
Please define "the natural frequency" of a molecule of water.
 
Natural frequency is the frequency at which a system tends to oscillate in the absence of any driving or damping force. Free vibrations of an elastic body are called natural vibrations and occur at a frequency called the natural frequency.

Now, assume we want to calculate the natural frequency of a single molecule of water in normal conditions: T = 25 °C and P = 1 atm

What is the procedure of the solution?

For starters, it does not make sense to talk about a single molecule at a given temperature and pressure.

If you are talking about about the vibrational frequencies of a molecule, then you would have to do quantum chemistry calculations or use a simplified mass-and-spring model.

But I have the feeling that this is not what you are after.
 

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...
