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.

Binford received a Ph. D. in particle physics in 1965 from the University of Wisconsin – Madison, under the supervision of Myron L. Good ; his thesis was entitled " Angular Distribution and Polarization of Neutral Hyperons Produced in Association with Neutral Kaons ".

Angular contact bearings better support " combined loads " ( loading in both the radial and axial directions ) and the contact angle of the bearing should be matched to the relative proportions of each.

The algebraic theory of spin is a carbon copy of the Angular momentum in quantum mechanics theory.

This `` ejection '' momentum is linearly related to the particle energy.

A consequence of using waveforms to describe particles is that it is mathematically impossible to obtain precise values for both the position and momentum of a particle at the same time ; this became known as the uncertainty principle, formulated by Werner Heisenberg in 1926.

In states where a quantum mechanical particle is bound, it must be localized as a wave packet, and the existence of the packet and its minimum size implies a spread and minimal value in particle wavelength, and thus also momentum and energy.

Particles cannot be restricted to a geometric point in space, since this would require an infinite particle momentum.

If denotes the quantum state of a particle ( n ) with momentum p, spin J whose component in the z-direction is σ, then one has

For the case of an object that is small compared with the radial distance to its axis of rotation, such as a tin can swinging from a long string or a planet orbiting in a circle around the Sun, the angular momentum can be expressed as its linear momentum,, crossed by its position from the origin, r. Thus, the angular momentum L of a particle with respect to some point of origin is

The angular momentum L of a particle about a given origin is defined as:

where r is the position vector of the particle relative to the origin, p is the linear momentum of the particle, and × denotes the cross product.

The angular momentum of a particle or rigid body in rectilinear motion ( pure translation ) is a vector with constant magnitude and direction.

If the path of the particle or centre of mass of the rigid body passes through the given origin, its angular momentum is zero.

The angular momentum of a collection of particles is the sum of the angular momentum of each particle:

It is the same angular momentum one would obtain if there were just one particle of mass M moving at velocity V located at the center of mass.

In the language of four-vectors and tensors the angular momentum of a particle in relativistic mechanics is expressed as an antisymmetric tensor of second order

Spin is often depicted as a particle literally spinning around an axis, but this is a misleading and inaccurate picture: Spin is an intrinsic property of a particle, fundamentally different from orbital angular momentum.

The Kerr Metric, corresponding to a black hole of mass and angular momentum, can be used to derive the effective potential for particle orbits restricted to the equator ( as defined by rotation ).

This could be done by sending a particle of angular momentum.

Because this particle has angular momentum, it can only be captured by the black hole if the maximum potential of the black hole is less than.

Testing other values shows that no particle with enough angular momentum to violate the censorship conjecture would be able to enter the black hole, because they have too much angular momentum to fall in.
