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.

i] can be seen as two parts: the inherent phase terms and the additional phase terms resulting from radial motion.
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 radial motion measured on FC500 under pulse excitation is shown in Fig.
However, as is well known, the illusion of radial motion can be created by changing the amplitude of the signal emitted from an immobile sound source (Vartanian & Chernigovskaia, 1980).
This type of motion in depth generates radial motion (expansion or contraction) in the retinal image.
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.
These sources are used as the reference in extracting the Doppler shift of the return signal, which is proportional to the radial motion of the target from which the transmitter signal is backscattered.
