Inertia and Energy.
=.
Newtonian conception of *inertia* says nothing about energy.
The idea * Inertia & Energy * was solved by Einstein.
In 1905 Einstein wrote paper:
 Does the inertia of a body depend upon its energy content?
As he realized the answer was:
 Yes, the inertia depends on its energy E= Mc^2.
It means, that the inertia (constant speed of photon) depends on E=Mc^2.

inertia and energy were formulated many years ago, the balistics formulas are quite similar to Einsteins formulas, but use velocity instead of the c (speed of light).

a) the energy E= Mc^2 is a "rest mass/energy"
b) the energy E= Mc^2 is responsible for inertial movement.
 Does the inertia of a body depend upon its energy content?
c) the energy E= Mc^2 can be very active and destroyed cities
like Hiroshima and Nagasaki.
d) there are positive and negative (+/-) E=Mc^2.
What is E=Mc^2 ?

To answer to the question *What is a E=Mc^2 ? *
one should analyze the derivation of this equation in the frameworks
of the SRT plus Dirac's equations plus QED plus
*The Law of conservation and transformation energy/ mass*

And if all else fails, multiply by the page number.
