Inverting Generalized Coordinates
In Corben's classical mechanics on pg. 9, it says that given generalized coordinates $q_m = q_m(x_1, ..., x_n,t)$, then if the Jacobian is non-zero everywhere, you may express $x_i = ...

Is the equivalence principle strictly fulfilled by general relativity?
The equivalence principle states
The outcome of any local experiment in a freely falling laboratory is independent of the velocity of the laboratory and its location in spacetime.
Any real local ...

Is spherical coordinates enough to calculate the exact position of a point with rotations included?
With "Geographic coordinate system" we only get the location, no rotations or anything. Translated into latitude and longitude.
Where with "Spherical coordinate system", we should be able to get the ...

Understanding P-, CP-, CPT-violation etc. in field theory and in relation to the principle of relativity
I can never get my head around the violations of $P-$, $CP-$, $CPT-$ violations and their friends. Since the single term "symmetry" is so overused in physics and one has for example to watch out and ...

Is General Relativity applicable for all coordinate systems?
My understanding was that relativistic physics can be expressed in any inertial coordinate system, but not arbitrary systems. That is, no experiment can determine if we are "still" or "moving" at a ...

Find radius of curvature, given a velocity vector and acceleration magnitude?
The particle P moves along a space curve. At one instant it has velocity $v = (4i-2j-k)$ $m/s$. The magnitude of the acceleration is 8 $m/s^2$. The angle between the acceleration and the velocity ...

Does change of coordinate system require acceleration?
This question came about from a side discussion that arose on this:
Does GR provide a maximum electric field limit?
Can we change our choice of coordinate system completely independent of physical ...

Is there any situation in Physics where the Right Hand Rule is not arbitrary?
We use Right Hand Rule in calculating Torque not because that's the direction torque is pointing in the real, physical world, but because it's a convenient way to indicate the "sign" of the rotation ...
