In the case of a central force, relative to the origin of the polar coordinate system, can be replaced by, meaning the entire force is the component in the radial direction.

Because of the absence of a net force in the azimuthal direction, conservation of angular momentum allows the radial component of this equation to be expressed solely with respect to the radial coordinate, r, and the angular momentum, yielding the radial equation ( a " fictitious one-dimensional problem " with only an r dimension ):

It is actually simply the outward radial component of the stone's inertia caused by its swing.

Only the radial component of the speed is relevant.

CW radar is ideal for determining the radial component of a target's velocity.

The radial velocity of Vega is the component of this star's motion along the line-of-sight to the Earth.

The radial component of this velocity — in the direction of the Sun — is − 13. 9 km / s, while the transverse velocity is 9. 9 km / s.

If B is a circle, then these eigenfunctions have an angular component that is a trigonometric function of the polar angle θ, multiplied by a Bessel function ( of integer order ) of the radial component.

However, the gyroradius ρ = mv / qB in those circumstances is also larger, so that the radial component of the magnetic field seen by the particle is also larger.

* Vector component, a term in the decomposition of a vector into various directions such as axial, radial or tangential

Hue is the angular component of the polar representation, while chroma is the radial component.

Two have already been discussed above, in the cases that either the radial components or the angular components are zero, and the non-zero component of motion describes uniform acceleration.

As shown in the diagram ( with angles ɸ and θ in radians ), if a line is drawn from the origin ( O ) to the particle ( P ), then the velocity ( v ) of the particle has a component along the radius ( radial component, v < sub >‖</ sub >) and a component perpendicular to the radius ( cross-radial component, v < sub >⊥</ sub >).

If there is no radial component, then the particle moves in a circle.

A radial motion produces no change in the direction of the particle relative to the origin, so for purposes of finding the angular velocity the radial component can be ignored.

This variation gives direct and highly accurate measurements of the radial component of a target's velocity relative to the radar.

In the special case of circular orbits, in order for the radial distance to remain constant the outward centrifugal force must cancel the inward force of gravity ; for other orbit shapes, these forces will not cancel, so r will not be constant.

Thanks to its radial road system, all of these routes touch Budapest.

These are often wound on a flat insulating support with radial spokes or slots, with the wire weaving in and out through the slots ; these are called spiderweb coils.

In reality, the Central Artery was the only one of these radial expressways that was fully completed.

Also encircling the basin is a pattern of radial grooves called the " Imbrium Sculpture ", which have been interpreted as furrows cut in the Moon's surface by large projectiles blasted out of the basin at low angles, causing them to skim across the lunar surface ploughing out these features.

The large frontal area of these aircraft meant the radial engine's own frontal profile was a less significant factor when it came to drag.

Instead these multipolar cells express neuronal markers and extend multiple thin processes in various directions independently of the radial glial fibers.

Unfold these two radial folds.

The right internal thoracic artery ( RITA ), the great saphenous vein from the leg and the radial artery from the forearm are frequently used ; in the U. S., these vessels are usually harvested endoscopically, using a technique known as endoscopic vessel harvesting ( EVH ).

Most bicycles use angular-contact bearings in the headsets because the forces on these bearings are in both the radial and axial direction.

For these lenses the field produced for the lens must be radially symmetric, as deviation from the radial symmetry of the magnetic lens causes aberrations such as astigmatism, and worsens spherical and chromatic aberration.

Because these definitions of saturation – in which very dark ( in both models ) or very light ( in HSL ) near-neutral colors, for instance or are considered fully saturated – conflict with the intuitive notion of color purity, often a conic or bi-conic solid is drawn instead (), with what this article calls chroma as its radial dimension, instead of saturation.

No complete aircraft as in the previous war but 50, 800 radial aero-engines — Bristol Mercury, Hercules and Pegasus — with full sets of parts for a further 9, 500 of these engines ; propeller shafts for Rolls-Royce aero-engines ; 14, 356 gun-turrets for bombers including their Browning machine guns ; 74, 000 Bren guns — bombed-out that production had to be moved to a boot and shoe factory in Burton-on-Trent.

In terms of these coordinates, the velocity of light at any point is the same in all directions, but it varies with radial distance r < sub > 1 </ sub > ( from the point mass at the origin of coordinates ), where it has the value

In sea stars these are always staggered, so that an ampulla on the left follows one on the right, and so on down the length of the radial canal.

The database determines shapes of ( atom-centered ) basis functions ( in fact radial part of these function ) optimised for one or the other criteria.

By convention, n corresponds to the number of nodes of the radial eigenfunction, l indicates the total number of nodal lines on spheres, and m tells how many of these nodal lines cross the equator.

Moreover, Lakoff gave a detailed accounting of how these schemas were interrelated in terms of what he called a radial category structure.

The expansion of space causes the spectra of these galaxies to be shifted, depending on the distance, and modified by the doppler effect of the galaxy's radial velocity.

Like the compound miter saw, the radial arm saw can make these cuts with absolute precision, but is capable of making a wider variety of cuts, including more complex ones.

# Add more non-sticky radial lines attached to these frame lines, in some cases adding at the same time less peripheral, " secondary " frame lines.

In these cases, a difference between the normal radial pulse in the right arm and the delayed femoral pulse in the legs ( either side ) may be apparent, whilst no such delay would be appreciated with palpation of both delayed left arm and either femoral pulses.

Due to higher radial and circumferential pressures within the vessel wall layers closer to the main lumen of the artery, vasa vasorum externa cannot perfuse these regions of the vessel wall ( occlusive pressure ).

The radial MK-1 produced a pulsed magnetic field of 25 megagauss ( 2500 teslas ).

A radial magnetic field established by magnets on the thruster is used to trap electrons which then orbit and create an electric field due to the Hall effect.

A radial current through a circular disc, subjected to a magnetic field perpendicular to the plane of the disc, produces a " circular " current through the disc.

A radial magnetic field of a hundred gauss ( about 100 – 300 G, 0. 01 – 0. 03 T ) is used to confine the electrons, where the combination of the radial magnetic field and axial electric field cause the electrons to drift azimuthally, forming the Hall current from which the device gets its name.

The central spike forms one pole of an electromagnet and is surrounded by an annular space and around that is the other pole of the electromagnet, with a radial magnetic field in between.

The radial magnetic field is designed to be strong enough to substantially deflect the low-mass electrons, but not the high-mass ions which have a much larger gyroradius and are hardly impeded.

The majority of electrons are thus stuck orbiting in the region of high radial magnetic field near the thruster exit plane, trapped in E × B ( axial electric field and radial magnetic field ).

A bank of capacitors releases a pulse of electric current lasting 10 microseconds into the coil, generating a radial magnetic field.

Within the range of gamma ray deposition, simple laws no longer hold as the air is ionised and there are other EMP effects, such as a radial electric field due to the separation of Compton electrons from air molecules, together with other complex phenomena.

The divergence of a vector field which is the resultant of radial inverse-square law fields with respect to one or more sources is everywhere proportional to the strength of the local sources, and hence zero outside sources.
