Let us note in passing that it would not be the first time that the kinetic action would be modified as special relativity
does just this too, changing for a single particle
in
(where
), leading for a
moving body to a redefinition of the effective mass as
. With this analogy in mind, a rather
simplified view of the Lorentz-breaking modification of inertia needed in order to reproduce MOND would be that
, where
is the amplitude of the acceleration with respect to an absolute preferred inertial
frame.
