proper motion

n.
A gradual change in the position of a star or other object on the celestial sphere that is the result of the object's intrinsic motion through space rather than mere apparent motion as observed from Earth.

proper motion

n
(Astronomy) the very small continuous change in the direction of motion of a star relative to the sun. It is determined from its radial and tangential motion

The aim of this article is to find the energy absorbed by the particle due to its intrinsic motion in the presence of zeropoint field and to discuss the possible origin of mass generation.
He and colleague Richard Sramek (NRAO) reached this conclusion by detecting no intrinsic motion of the source across our line of sight during observing runs with the Very Large Array between 1981 and 1986.
Kersten examines coding processes involving motion events and puts forward the thesis that there is a "division of labor" between nouns and relational terms in describing motion events, showing the tendency to code intrinsic motion (information on the manner of motion), while the prototypical relational term codes motion with reference to an external frame of reference, for example, path information.
It may be hypothesized "whether learning to shift attention toward intrinsic motion in the context of verb learning encourages English speakers to generally attend more strongly to the manner of motion than do Spanish speakers, even outside of a verb-learning context," and Kersten supposes this might be a consequence of the "linguistic relativity hypothesis (...), which suggests that one's language influences one's perception and conception of the world" (Kersten, this issue).
Likewise, although the intrinsic rest mass 0[m.sup.0.sub.0] in [phi][[rho].sup.0'] acquires the intrinsic speed [phi][V.sub.0] = [phi]c of [phi][[rho].sup.0'], it is not in intrinsic motion at the intrinsic speed [phi]c along [phi][[rho].sup.0'], since the intrinsic speed [phi]c it acquires is an absolute intrinsic speed.
The observations made from system (2) and system (3) described in the foregoing paragraph make the concept of intrinsic affine spacetime induction relevant in relative intrinsic motion of two intrinsic spacetime frames of reference.
According to this theory, nouns tend to convey intrinsic motion, or motion defined with respect to a frame of reference internal to the object carrying it out.
When path-specifying verbs are used, there is a clear division of labor between nouns and verbs, with verbs conveying extrinsic motion and nouns conveying intrinsic motion. For example, in the Spanish sentence El conejo entro al hueco 'The rabbit entered the hole', the verb conveys the extrinsic motion of the rabbit with respect to the hole.
8a and 8b of [1], assuming rotation of intrinsic affine spacetime coordinates [phi][??]' and [phi]c[phi][??]' of the particle's intrinsic frame relative to the intrinsic affine spacetime coordinates [phi][??] and [phi]c[phi][??] of the observer's intrinsic frame by intrinsic angle [phi][psi] = [pi]/2, corresponding to intrinsic speed [phi]v = [phi]c of relative intrinsic motion, can be avoided in the process of rotation by [phi][psi] > [pi]/2.
7 of [3]), is the intrinsic mass relation in the context of absolute intrinsic motion to be derived formally elsewhere.
As the inertial mass m moves at velocity [??] in the Euclidean 3-space [SIGMA] of the flat four-dimensional spacetime ([SIGMA], ct) relative to an observer in ([SIGMA], ct), the intrinsic mass [phi]m performs intrinsic motion at intrinsic speed [phi][upsilon] in the one-dimensional intrinsic space [phi][rho] of the flat two-dimensional intrinsic spacetime ([phi][rho], [phi]c[phi]t) relative to the observer in ([SIGMA], ct), where [absolute value of [phi][upsilon]] = [absolute value of [??]].
Functional range of motion around the elbow is necessary for daily living and hygiene and more intrinsic motions of contemporary society.
