AI Thread Summary
In the context of air drag, nonconservative work (Wnonconservative) primarily contributes to the energy used in displacing air molecules. This energy ultimately transforms into heat, as energy conversion is a fundamental principle. Additionally, sound energy generated during the process also dissipates as heat. Therefore, both heat and sound can be considered forms of energy resulting from air drag. Understanding these conversions is crucial in analyzing the effects of nonconservative forces.

Can someone please tell me where Wnonconservative goes in the case of Air drag? Does it go into heat and sound, or just heat or other types of energy?

Thank you!

It goes to pushing the air molecules out of the way. Eventually, that energy does become heat, as all energy must.
 
Sound eventually becomes heat, so you can call it either.
 

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...
