A spacecraft could rendezvous with one end of the tether, latch to it, and be accelerated by the tether's rotation.

The gyro angular momentum is defined by H.

When a beam of silver atoms was passed through a specially shaped magnetic field, the beam was split based on the direction of an atom's angular momentum, or spin.

Atomic orbitals are typically categorized by n, l, and m quantum numbers, which correspond to the electron's energy, angular momentum, and an angular momentum vector component, respectively.

The simple names s orbital, p orbital, d orbital and f orbital refer to orbitals with angular momentum quantum number l = 0, 1, 2 and 3 respectively.

However, the idea that electrons might revolve around a compact nucleus with definite angular momentum was convincingly argued at least 19 years earlier by Niels Bohr, and the Japanese physicist Hantaro Nagaoka published an orbit-based hypothesis for electronic behavior as early as 1904.

Shortly after, in 1913, Rutherford's postdoctoral student Niels Bohr proposed a new model of the atom, wherein electrons orbited the nucleus with classical periods, but were only permitted to have discrete values of angular momentum, quantized in units h / 2π.

In our current understanding of physics, the Bohr model is called a semi-classical model because of its quantization of angular momentum, not primarily because of its relationship with electron wavelength, which appeared in hindsight a dozen years after the Bohr model was proposed.

The azimuthal quantum number,, describes the orbital angular momentum of each electron and is a non-negative integer.

This gyroscope remains upright while spinning due to its angular momentum.

In physics, angular momentum, moment of momentum, or rotational momentum is a vector quantity that represents the product of a body's rotational inertia and rotational velocity about a particular axis.

The angular momentum of a system of particles ( e. g. a rigid body ) is the sum of angular momenta of the individual particles.

For a rigid body rotating around an axis of symmetry ( e. g. the blades of a ceiling fan ), the angular momentum can be expressed as the product of the body's moment of inertia, I, ( i. e. a measure of an object's resistance to changes in its rotation rate ) and its angular velocity ω:

In this way, angular momentum is sometimes described as the rotational analog of linear momentum.

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

My unscientific friend does not believe that human stature is measurable in terms of speed, momentum, weightlessness, or distance from earth, but is a matter of the development of the human mind.

Many workers believe that the response is proportional to the incident momentum of the particles, a relation deduced from laboratory results linearly extrapolated to meteoritic velocities.

The Russian experimenters claim that only a small fraction of the impulse from the sensors is caused by the incident momentum with the remainder being momentum of ejected material from the sensor.

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

The threshold mass is derived from the momentum threshold with the assumption of a mean impact velocity of Af in the U.S. work and Af in the U.S.S.R. work.

The mass scale used in Table 5-1 was derived on the assumption that the motion of the glowing trail is related to the momentum transfer to the trail by the meteorite, permitting the calculation of the mass if the velocity is known ( Cook and Whipple, 1958 ).

As the ship moves, momentum is not conserved – the ship eventually comes to a stop again when not thrusting.

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.

With de Broglie's suggestion of the existence of electron matter waves in 1924, and for a short time before the full 1926 Schrödinger equation treatment of hydrogen like atom, a Bohr electron " wavelength " could be seen to be a function of its momentum, and thus a Bohr orbiting electron was seen to orbit in a circle at a multiple of its half-wavelength ( this historically incorrect Bohr model is still occasionally taught to students ).

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.

The single-photon annihilation of an electron-positron pair, + →, cannot occur in free space because it is impossible to conserve energy and momentum together in this process.

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

* Conservation of Momentum: This equation applies Newton's second law of motion to a continuum, whereby force is equal to the time derivative of momentum.

The heavily favored Cubs took an early lead in Game 1, but James Loney's grand slam off Ryan Dempster changed the series ' momentum.

This changed the momentum as South Africa secured wins in Durban and Cape Town, where Cronje scored his fourth test century, he was the first captain since W. G. Grace to win a three-match rubber after being one down.

With the Giants leading 5 – 0 going into the bottom of the 7th inning of Game 6, the series ' momentum changed decisively when then Manager Dusty Baker removed starter Russ Ortiz and handed him the " game " ball as he left the mound.

Ratnam maintained a momentum of making emotional stories of under-served people through the film Anjali in 1990, which starred Raghuvaran and told the story of an autistic child who changed the lives of people around her.

The decisive naval / aerial Battle of Midway that took place in early June 1942, however, changed the momentum of the war.

Since light has a momentum associated with it, this change in direction indicates that its momentum has changed.

Beginning in 1950, the show's momentum changed as the legendary CBS talent raids of the time began to take their toll.

As with energy and momentum, the invariant mass of a system cannot be destroyed or changed, and it is thus conserved, so long as the system is closed.

Though hailed as a great success in the 1970s, the movement lost momentum during the 1980s as economic situation and political environment in South Korea changed rapidly.

Although the Saemaul Movement has achieved a great success in reducing poverty and improving living conditions in rural areas, rapid industralization of South Korea changed the environment and diminished the momentum of the movement.

Also changed out was one of four Reaction Wheel Assembly units that use spin momentum to move telescope toward a target and maintain it in a stable position.

After the Braves had blown 5-0 and 7-3 leads in Game 6 and trailed 8-7 in the 8th inning, Nixon pinch ran at 1st base with 1 out and changed the momentum of the game and the series by stealing second and going to third when the throw went into center field.

The bungled Russell / Jackson play changed the game and the entire Series ; instead of the Dodgers going up 3 – 1 in games, the Series was then tied and the momentum shifted to the Yankees who outscored the Dodgers 19 – 4 in the final two games.

Like energy and momentum, the invariant mass of isolated systems cannot be changed so long as the system remains totally closed ( no mass or energy allowed in or out ), because the total relativistic energy of the system remains constant so long as nothing can enter or leave it.

Leyritz is best known for hitting numerous postseason home runs that either won, tied, or changed the momentum of several series.
