absolute motion

[′ab·sə‚lüt ′mō·shən]

(physics)
Motion of an object described by its measurement in a frame of reference that is preferred over all other frames.

The ether-drift experiment and the determination of the absolute motion of the earth.
In simulations, absolute motions of the spacecraft and asteroid in the inertial space will be simulated separately.
In order to derive the absolute velocity [V.sub.M/E] of payload M we will apply the vector method for absolute motion assignment.
Also the period of the modulation based on a fixed absolute motion vector in the Miller direction would not be 12 sidereal hours but 24 as can be plainly seen from the geometry.
Let us suppose for example, that the absolute motion of the platform is a 3-D rotation around the fixed point O, defined by the Euler angles
His famous argument at the end of the Scholium concerning the rotating bucket is usually interpreted as an attempt to provide a criterion (at least for the case of circular motion) for absolute motion or rest.
It is relativity, because velocity has meaning only as relative to an observer, there being no such thing as "absolute rest" against which an "absolute motion" can be measured.
Defined in these terms, length contraction and time dilation constitute real processes of dynamic origin, connected with the impact of absolute motion on molecular forces.
That is, perhaps Newton and Leibniz agreed on the physically objective status of simultaneity and instantaneous Euclidean geometry--enough structure to define relative motion--but absolute space adds something to that structure that allows us to describe absolute motion, and one could claim that adding that structure is tantamount to changing the ontological status of space.
The Dynamical 3-Space theory was applied to an experiment which studied the radio frequency (RF) electromagnetic (EM) speed anisotropy, or ultimately the absolute motion of Earth through space.
Results from Michelson-Morley [3,4], Miller [5], Torr and Kolen [6] and DeWitte [7], are now in remarkable agreement with the velocity of absolute motion of the earth determined from NASA spacecraft earth-flyby Doppler shift data [8,9], all revealing a light/EM speed anisotropy of some 486km/s in the direction RA=[4.29.sup.h], Dec=-75.0[degrees]: that speed is ~300,000-500 km/s for radiation travelling in that direction, and ~300,000+500 km/s travelling in the opposite, northerly direction: a significant observed anisotropy that physics has ignored.
This shows that (i) the matter "gravitational" geodesic is a quantum wave refraction effect, with the trajectory determined by a Fermat maximum proper-time principle, and (ii) that quantum systems undergo a local time dilation effect caused by their absolute motion wrt space.
