Is a Maxwell Velocity Distribution Possible in a Newtonian Gravitational Field?

AI Thread Summary
A Maxwell velocity distribution can be derived for particles in a Newtonian gravitational field by expressing it as a distribution of energies. By substituting the energy equation E=mv^2/2 + mgz, it can be reformulated as a function of velocity and height above the ground. This approach can also be adapted for a 1/r^2 gravitational field, although the energy expression becomes more complex. While this theoretical framework is sound, practical implementation may present challenges. Overall, the concept is feasible with the right mathematical adjustments.

hi,

I asked myself, whether it would be possible, to derive something like a maxwell velocity distribution for particles that are placed in a Newtonian gravitational field?

Does anybody know whether this is generally possible?

Yes - Express the Maxwell distribution as a distribution of energies, and then substitute E=mv^2/2+mgz and express it as a function of velocity and height z above the ground. Same idea if you want to do it in a 1/r^2 gravitational field, except the energy is more complicated. I've never done it, so you might run into some gliches.
 
Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'
So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
It may be shown from the equations of electromagnetism, by James Clerk Maxwell in the 1860’s, that the speed of light in the vacuum of free space is related to electric permittivity (ϵ) and magnetic permeability (μ) by the equation: c=1/√( μ ϵ ) . This value is a constant for the vacuum of free space and is independent of the motion of the observer. It was this fact, in part, that led Albert Einstein to Special Relativity.
