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 sum of the angular momenta of the individual particles: \bar L=\sum \bar L_{i...

The total angular momentum of a multicomponent system is calculated by adding the individual angular momenta of each component. This can be done using vector addition, taking into account the direction and magnitude of each component's angular momentum. What factors affect the angular momentum of a...

11.2 Angular Momentum Learning Objectives By the end of this section, you will be able to: Describe the vector nature of angular momentum Find the total angular momentum and torque about a designated origin of a system of particles Calculate the angular momentum of a rigid body rotating about ...
Angular momentum is momentum rotating around an axis. It is also a vector having direction as well as magnitude. It is the product of inertia (of the mass) and its angular velocity. How far the mass is located from the axis critically affects angular momentum (Fig. 1.2.2b). The symbol...
This model also gives a natural explanation for the quadratic scaling of angular momentum with mass. Again, from this model, the background torsion due to a universal spin density not only give rise to angular momenta for all structures but also provide a background 'centrifugal term' acting ...
