I Synchronizing clocks in an inertial frame if light is anisotropic

[Dale]

I would agree with that view. There are no non-zero Christoffel symbols in an Anderson frame, hence no fictitious forces. So Newton’s first law is satisfied.

But I would still not consider it to be an inertial frame for that reason. There are Anderson-frame expressions for conserved energy and momentum, but they differ enough that I don’t think the second and third laws are useful in such frames.

A calorimeter doesn’t measure KE.

If it is at rest in the center of mass frame and we have arranged for a fully inelastic collision to happen inside it?
