Its magnitude is L= rp sin θ, where θ is the angle between r and p; its direction is specified by the right-hand rule for vector products (see Chapter 1). The units of angular momentum are kg·m2/s or slug·ft2/s. We will concentrate on simple rotational systems in which ...
Definition In mechanics, angular momentum is the vector cross product between the position vector and the momentum vector of a point mass system. This definition can be extended to a solid by summation. Overview The movement of a point massmis defined by its positionrand its velocityv. These q...
Angular momentum is a vector quantity, which means that it has always a certain orientation in space, depending on the direction of rotation. For the rotation indicated in Figure 11.3(a), the vector can only point upwards. It would not help to turn the picture upside down because the coupli...

Furthermore, the expression is valid for any origin fixed in an inertia frame. 也就是说,当没有torque的时候, d\bar L/dt=0, angular momentum为常量。 Angular momentum of a system of particles The total angular momentum of a system of particles about some point is defined as the vectors ...

angular momentum n. 1.The vector product of the position vector (from a reference point) and the linear momentum of a particle. 2.The vector sum of the angular momentums of each infinitesimal component particle of an extended body.
As in classical mechanics, rotation in quantum mechanics is a transformation which deals with angular momentum. The difference with classical mechanics comes from the fact that angular momentum is a vector operator and not a usual vector and its components do not commute. As for any transformation...
