Both the inertial mass
and cover correspond to rigid bodies and possess equal rigidity in all directions.
In this section, we show that the inertial mass
of a body is its proper mass while the relativistic mass m* is in effect an effective mass or, as Dixon  refers to it, an apparent mass.
(2) In 1907 Plank  criticized the Einstein argument, and presented his own argument to show that the transfer of heat is associated with a similarly related transfer of inertial mass
It has been argued that for there to be correspondence with the particle mass, perhaps at pre-quantum level, inertial mass
must originate from external electromagnetic interaction .
For example that the inertial mass
of photons is finite and varies in line with MiHsC.
This has physicists puzzled, but it could be explained if gravitational mass was not the same as inertial mass
, which is a paradigm in physics.
To sum up, the inertial mass
in magnetic fluid accelerometers can be one out of nonmagnetic body, magnet, or magnetic fluid.
where, respectively, m and m|prime~ are the alumiunum gravitational mass and the platinum one, whereas n and n|prime~ are the aluminium inertial mass
and the platinum one.
The absorber can be completed by fixing an inertial mass
near the free end of the member.
This is called the inertial mass
, because the greater the mass of a body, the less acceleration a given force produces and the greater the inertia (the resistance to a change in velocity).
It features low inertial mass
, crosstalk of less than 2 percent and high stiffness in both axis.
Gravity Probe A, in June 1976, was a suborbital flight of an atomic clock to test the equivalence of gravitational and inertial mass
, another key element of Einstein's theory of gravity.
