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。（ ）

As external force is zero. P is constant but K.E. increases. Due to external torque, angular momentum changes. P.E. also changes.
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...
