What's then the difference between inertial mass and relativistic mass?

Hmmm. are you meaning rest mass is the inertial mass?

I'm primarily interessted in the definitions according to classical
mechanics.

Hmmm... a large part of the 'rest mass' of a proton, for example, is derived
by the relativistic motion of the particles that make it up. A reason why
the electron is so light, according to this thinking, is because it is truly
fundamental, and its mass is derived solely by interaction with the Higgs
mechanism. So, what is rest mass, and how does it differ from relativistic
mass? Have an idea? Then throw your coin into the ring and contribute.

Ideas? Lots but you won't like them.

There is a steady flow of energy in all directions
through everything. There are actually
many different flows, especially cell phones around Earth, but
I am only talking about the energy responsible for
causing inertia and gravity and 'mass'.

This energy is taken in at a steady rate by protons
to keep them discrete. Protons are standing waves
where to move the energy in a different
way would require so much more energy that it
just doesn't happen, but they create electrons, which
radiate, and therefore protons steadily use energy at a
certain rate. This energy absorption, for a large
number of protons, takes place from all directions at once,
so 'rest mass' is equal from all directions.

So, briefly, to go on and describe
gravity, one interposes the planet,
which absorbs a part of the energy, leaving less
available so less 'push' from that direction.
So matter has less inertia in a planetary direction
and will move that way if unsupported.

Now increase the size of the planet so it
approaches absorption of all energy having an
outward impetus. (This will be impossible
with any curvature.)
The matter gains less and less mass as a
theoretical planet increases in size until it
is approaching but never getting to a limit.
THE MATTER DOES NOT ATTAIN INFINITE
MASS UNDER ANY CIRCUMSTANCES.

A body's self-gravity approaches a limit
which is totally dependent on the steady flow
of energy in all directions through everything.
It can only be as large as ZERO energy coming
from the other direction.

Now, if instead of blocking all the flow
coming from one direction, we move the
mass in one direction faster and faster.
Apparently the faster one tries to move it,
the more energy is needed per increment in speed.
Is this in agreement with less energy
flow moving from behind and more energy flow
coming from in front?

Whatever.
