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: 这个部分在mit公开课中讲的比较简明。关键点在于,角动量也好,torque也好,都是相对某一点而言的。选择不同的...

The angular momentum is an axial vector directed along the axis of rotation. The specific direction of the angular momentum can be determined by applying the right-hand thumb rule.Answer and Explanation: Let L→ be the instantaneous vector sum of the angular momentum of a system consistin...
握手也有先后顺序，应由主人、年长者、身份高者、妇女先伸手，客人、年轻者、身份低者见面先问候，待对方仲出手后再握。多人同时擂手，切忌交叉进行，应等别人握手完毕后再伸手。男子在握手前应先脱下手套，摘下帽子。握手时应双目注视对方，微笑致意。（ ）

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...
Units for linear momentum are kg ⋅ m/s while units for angular momentum are kg ⋅ m2/s. As we would expect, an object that has a large moment of inertia I, such as Earth, has a very large angular momentum. An object that has a large angular velocity ω, such as a centrifuge...
