Angular momentum is conserved in a system where there is no net external torque, and its conservation helps explain many diverse phenomena.

Angular momentum is also known as moment of momentum.

Angular momentum in terms of scalar and vector components.

Angular momentum in quantum mechanics differs in many profound respects from angular momentum in classical mechanics.

Angular momenta of a classical object .< p > Left: intrinsic " spin " angular momentum S is really orbital angular momentum of the object at every point ,</ p >< p > right: extrinsic orbital angular momentum L about an axis ,</ p >< p > top: the moment of inertia tensor | moment of inertia tensor I and angular velocity ω ( L is not always parallel to ω )</ p >< p > bottom: momentum p and it's radial position r from the axis .</ p > The total angular momentum ( spin + orbital ) is J.

The eigenvalues for Angular momentum operator:

Angular momentum conservation prevents a straight flow from one star to the other and an accretion disc forms instead.

* 2004 — The Degree Angular Scale Interferometer ( DASI ) first obtained the E-mode polarization spectrum of the cosmic microwave background radiation.

* Angular magnification — For optical instruments with an eyepiece, the linear dimension of the image seen in the eyepiece ( virtual image in infinite distance ) cannot be given, thus size means the angle subtended by the object at the focal point ( angular size ).

It received considerable negative criticism upon its release — a release which RCA, anxious to maintain the established commercial momentum, did not welcome, and which Bowie's ex-manager, Tony Defries, who still maintained a significant financial interest in the singer's affairs, tried to prevent.

With this additional condition — the covariant divergence of the energy – momentum tensor, and hence of whatever is on the other side of the equation, is zero — the simplest set of equations are what are called Einstein's ( field ) equations:

Analog computers take advantage of the strong similarities between the mathematics of small-scale properties — the position and motion of wheels or the voltage and current of electronic components — and the mathematics of other physical phenomena, for example, ballistic trajectories, inertia, resonance, energy transfer, momentum, and so forth.

For example, a heavy truck moving fast has a large momentum — it takes a large and prolonged force to get the truck up to this speed, and it takes a large and prolonged force to bring it to a stop afterwards.

The momentum theory or disk actuator theory — a theory describing a mathematical model of an ideal propeller — was developed by W. J. M.

The purpose of using pole weapons is either to extend reach or to increase angular momentum — and thus striking power — when the weapon is swung.

It was found that for silver atoms, the beam was split in two — the ground state therefore could not be integral, because even if the intrinsic angular momentum of the atoms were as small as possible, 1, the beam would be split into 3 parts, corresponding to atoms with L < sub > z </ sub > = − 1, 0, and + 1.

Modern battering rams sometimes incorporate a cylinder, along the length of which a piston fires automatically upon striking a hard object — thus enhancing the momentum of the impact significantly.

From the perspective of quantum theory, light is made of photons: particles with zero mass but which carry energy and — importantly in this argument — momentum.

The momentum the photons carry is a conserved quantity — that is, it cannot be destroyed — so it must be transferred to the surface ; the result is that absorbing the light beam causes the surface to gain momentum.

After 1850 the Shakers lost their momentum and added only occasional new members — usually orphans left in their care.

The uncertainty principle actually describes how precisely we may measure the position and momentum of a particle at the same time — if we increase the accuracy in measuring one quantity, we are forced to lose accuracy in measuring the other.

Durkheim's use of the term anomie was about a phenomenon of industrialization — mass-regimentation that could not adapt due to its own inertia — its resistance to change, which causes disruptive cycles of collective behavior ( e. g. economics ) due to the necessity of a prolonged buildup of sufficient force or momentum to overcome the inertia.

" Dramatically, I just felt like Marquesas never got any momentum, and by the time you got to the final two with Neleh and Vecepia — I'm sleeping.

On the other hand, England, England is the story of Sir Jack Pitman's gigantic project of draining England of everything that is essentially English ( including the royals ), reassembling it on the Isle of Wight and turning that island into an independent member state of the European Union — a project which quite soon develops its own momentum and which survives its founding fathers and mothers.

The physical system itself need not be symmetric ; a jagged asteroid tumbling in space conserves angular momentum despite its asymmetry — it is the laws of its motion that are symmetric.
