AI Thread Summary
Energy cannot be transferred from one form to another without performing work, as work is inherently linked to energy transfer. The discussion highlights that while heat can transfer energy, it still involves work at the microscopic level, particularly concerning the atoms of the cooler material. This concept is often simplified by focusing on macroscopic systems and overlooking the microscopic interactions. The relationship between work and energy transfer is fundamental in thermodynamics. Overall, energy transfer without work is not feasible when considering the complete system dynamics.

Since work is responsible for transfer of energy from one form to other,is it possible to transfer energy from one form to other without doing work.

It is not. Whenever work is performed, energy is transferred. Whenever energy is transferred, work is performed.

Yes, that is called "heat".

Are we ignoring the work performed on the atoms of the cooler material when the energy is transferred?

Yes, essentially by definition. It is really a tautology that comes about by ignoring the microscopic degrees of freedom and only looking at the macroscopic system.

Ah ok. I figured as much, I just wanted to make sure and to be clear so that the OP doesn't get confused.
 

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...
