radial motion

radial motion

[′rād·ē·əl ′mō·shən]
(mechanics)
Motion in which a body moves along a line connecting it with an observer or reference point; for example, the motion of stars which move toward or away from the earth without a change in apparent position.

This radial motion is used to align the transfer arm with the desired chamber port achieving angular reproducibility of <0.
Computer simulations of galaxy formation normally show an increasing tendency towards radial motion if one moves further out in the halo.
In studying the radial motion through the event horizon (a black hole's boundary) of two different types of black holes--Schwarzschild and Einstein-Rosen, both of which are mathematically legitimate solutions of general relativity--Poplawski admits that only experimentation or observation can reveal the motion of a particle falling into an actual black hole, but he also notes that, since observers only can see the outside of the black hole, the interior cannot be viewed unless someone (or something) enters or resides within.
This therapeutic device has a sophisticated and advanced irrigation system employing hydrodynamic cavitation producing transient radial motion of bubbles wherein the individual manipulates the hand piece of the sealed eye cup irrigator to wash or remove gunk's from his/her eyes.
The mixing elements are arranged at intervals on the mixer shaft and their size, number, arrangement, geometric shape and peripheral speed are designed to force the product into appropriate components of axial and radial motion.
By 2005, scientists expect RAVE to have measured the radial motion of 100,000 stars.
For example, a pan shot will lead to strong lateral motion, and a zoom leads to a radial motion field.
The radial motion of an average-sized spindle face, not so long ago, was 0.
However, as shown in several papers [2, 3, 4, 7, 8], Birkhoff's theorem is, in fact, a vicious circle arising from the introduction of inadmissible implicit transformations which eliminate in advance the boundary conditions defining the radial motion of the sphere bounding the matter, namely the boundary conditions inducing the non-stationary states of the gravitational field.
In a rotating spiral galaxy, such a radial motion would alter the velocities of hydrogen atoms distributed in vast sheets moving with the galaxy.
Campbell and his co-workers arestudying radial motion.
s]] are the velocity correlations due to particle collisions and induce momentum swap in the longitudinal and radial motions of the given fraction (Kartushinsky and Michaelides, 2004).
