  Newton's second law has limited scope of application when transient phenomena
are present. We consider a modification of Newton's second law in order to take
into account a sudden change (surge) of angular momentum or linear momentum. We
hypothesize that space itself resists such surges according to a kind of
induction law (related to inertia); additionally, we provide further evidence
of the "fluidic" nature of space itself. This "back-reaction" is quantified by
the tendency of angular momentum flux threading across a surface. This quantity
is mass-dependent, and bears similarity to the quantum mechanics phase shift,
present in the Aharonov-Bohm and Aharonov-Casher effects. Furthermore, this
provides evidence of vacuum polarization, a phenomena which is relative to
local space indicating that local geometry and topology should be taken into
account in any fundamental physical theory.
