Sentence examples for momentum vector from inspiring English sources

The quantization of the orientation of the angular momentum vector was confirmed in an experiment in 1922 by other German physicists, Otto Stern and Walther Gerlach.

As precession proceeds, the torque remains horizontal, and the angular momentum vector, continually redirected by the torque, executes uniform circular motion in the horizontal plane at a frequency Ω, the frequency of precession.

The first half is devoted to a simultaneously sketchy and ponderous history of 20th-century physics, full of such technical jargon as "mixing angles," "perturbation expansions" and "conformal transformations," packed into sentences like "the operator corresponding to an angular momentum vector is precisely the one that implements an infinitesimal rotation about the axis given by that vector".

The surrounding magnetic field (symbolized by the vector H) exerts a torque that tends to bring μ and H into alignment, but this torque also interacts with the angular momentum vector; the effect of this interaction is to cause the spin axis (and the magnetic-moment vector) to undergo the so-called Larmor precession, that is, to describe a cone about the direction of the magnetic field.

The initial momentum vector must be chosen to realize a classical path.

Transverse momentum is the component of the momentum vector projected onto the plane perpendicular to the beams.

"Reaction Microscopes" enable to detect the momentum vectors of several electrons and ions after the fragmentation of atoms or molecules.

During the recovery maneuver, the angular velocity and angular momentum vectors become aligned with the minimum axis of inertia by turning over about 90° in the body frame.

Next, (mathbf {p}) and (mathbf {p}') are the cosmic ray momentum vectors defined in the shock rest and plasma rest frames, respectively.

It is convenient to choose the spin polarization direction parallel to the z axis and express the momentum vectors in this coordinate system.

where C kq (θ r, φ r ) are the modified spherical harmonics and the angles ω t  = θ t, φ t and ω r  = θ r, φ r refer to the coordinates of the unit vectors k' and j' along the directions of the product relative velocity and rotational angular momentum vectors, respectively.
