## inertial mass

n
(General Physics) the mass of a body as determined by its momentum, as opposed to gravitational mass. The acceleration of a falling body is inversely proportional to its inertial mass but directly proportional to its gravitational mass: as all falling bodies have the same constant acceleration the two types of mass must be equal

The inner ring of the Stewart platform was equipped with an inertial mass for measuring 6-DOF acceleration, and the Stewart 6-DOF force sensor, in the outer ring, measured the 6-DOF force.
Some authors [11] suggest that rest-mass should be denoted as m as this is the real measure of inertial mass. The relativistic mass of an object corresponds to the total energy of an object (invariant proper mass plus kinetic energy).
We imagine that the amount of inertial mass of the electron ([m.sub.e]) is proportional to the five-dimensional volume of the unit cell in the momentum space lattice, which size is given by the Planck's characteristic momentum, namely
Now, recall that the inertial mass [m.sup.I] and passive mass mp are related to the rest mass [m.sub.0] of a particle by
The relativity rests on physical intuitions about the behavior of masses in a gravity field and in accelerated systems; it postulates the equivalence between gravitational and inertial mass and aims to build a covariant model of physical laws under transformation between inertial and non-inertial reference systems.
On this, Stachel [7] wrote, "Einstein returned to the relation between inertial mass and energy in 1906 and in 1907 giving more general arguments for their complete equivalence, but he did not achieve the complete generality to which he inspired.
Inertial mass and vacuum fluctuations in quantum field theory.
* have been calculated, using MBS software, the inertial mass characteristics, all body's mass and center of mass position;
McCulloch (2007) has proposed a new model for inertial mass that assumes that the inertia of an object is due to the Unruh radiation it sees when it accelerates, radiation which is also subject to a Hubble-scale Casimir effect.
The principle of equivalence states that a body's inertial mass, which determines how it responds to forces, is the same thing as its gravitational charge, the quality that determines the size of the gravitation force it exerts.
"Most physicists disagree with this because they believe that gravitational mass exactly equals inertial mass," Lebed said.
Magnetic fluid was set between the reference electrodes and the detection electrodes as the inertial mass. Thereby the accelerometer can be detected while the magnetic fluid moves in the horizontal plane by means of a change in the capacitance between electrodes.
