comment Conservative Forces & Conservation of Energy?
Note that with both conservative and non-conservative forces, energy is conserved. However, the potential energy of a non-conservative field is not possible to express as a function simply of co-ordinates.

comment Proof that flux through a surface is independent of the inner objects' arrangement
This is only true for point charges, not the general case. Also, the part of your answer after the comma essentially restates the question.

comment Why is $\phi$ constant in the hyperbolic Lorentz transforms?
I make that point in my question and it doesn't follow from that that $\phi$ doesn't depend on the two spacetime co-ordinates being studied.

comment Why is $\phi$ constant in the hyperbolic Lorentz transforms?
Thank you. Can the analogy between Euclidean and Minkowski space (specifically, the transformations) be made more rigorous? For instance, this question I asked on MSE seemed to indicate that there's not much geometric analogy to be made between hyperobolic and usual trigonometric functions, which makes me dubious of such analogies.

comment Why is $\phi$ constant in the hyperbolic Lorentz transforms?
Part of my problem may arise from assuming that the only reason for $(1),(2)$ is $(*)$: I don't know whether that assumption is correct.

comment Relative angular velocity and acceleration
@ja72 Yes, here, although I'm less sure that my interpretation of $\alpha$ as a cross product is correct.
