Hhokhani reacted to Chestermiller's post in the thread High School Internal energy and gravitation with
Like.
The more general form of the 1st law of thermodynamics is $$\Delta U+\Delta (PE)+\Delta (KE)=Q-W$$where PE is the gravitational... -
Hhokhani replied to the thread High School Electron absorbs photon, but what happens to the photon?.Is this wave function calculated by Hamiltonian?

Hhokhani reacted to gyorgiy's post in the thread High School Internal energy and gravitation with Like.
The crucial word in this context is "internal". If you include interactions with external objects, it no longer differs from total...
-
Hhokhani replied to the thread High School Internal energy and gravitation.Yes. Thanks all. Your comments resolved the ambiguity about internal energy and potential energy.

Hhokhani reacted to Herman Trivilino's post in the thread High School Internal energy and gravitation with Like.
You need at least two objects (usually modeled as particles) interacting with each other (via a conservative force) to have potential...

Hhokhani reacted to PeroK's post in the thread High School Electron absorbs photon, but what happens to the photon? with Like.
In QFT (Quantum Field Theory) photons are described by the quantized EM field. Or, perhaps it's better to say that the Quantum Field...

Hhokhani replied to the thread High School Electron absorbs photon, but what happens to the photon?.Does photon have wave function?
-
Hhokhani replied to the thread High School Internal energy and gravitation.The potential by its own is not physicaly meaningful and it is the potential difference which is important. We can choose any point as...

HWhen a mass M and a much smaller mass m, are released to fall towards eachother, then in the common center of mass frame, the...

Potential energy of one object is indeed zero. I agree with that but don't understand what you mean by an origin or by "another point"...

Hhokhani reacted to Andrew Mason's post in the thread High School Internal energy and gravitation with Like.
The internal energy is a thermodynamic property of a system and it is a function of its thermodynamic state. If the work done on the...
-
Hhokhani replied to the thread High School Internal energy and gravitation.Usually in elementary physics text book, dealing with energy concept is in such a way that we first choose a reference frame for kinetic...

Hhokhani reacted to Herman Trivilino's post in the thread High School Internal energy and gravitation with Like.
Here's the problem. Textbooks and instructors often refer to the gravitational potential energy of an object, such as a ball or in your...
-
HThis is obviously not specific enough. For example, kinetic energy is frame dependent, so you always have to provide the reference...
-
Hhokhani replied to the thread High School Internal energy and gravitation.Thanks, but as I read in some references, internal energy is equal to the sum of the average kinetic and potential energies of all...
