利用微课学习在中国是比较新的事物,通过视频学习有利于培养同学们的自主学习能力。同学们要自己把握学习节奏,听不懂的地方可以按一下暂停键,遇到新知识就记一下笔记,必要的时候可以再看一遍。在美国有可汗学院,中国类似的机构还没有。我相信在不远的未来,这类公益的教
The dimensional formula of angular momentum is [M^(1)L^(2)T^(-1)]. Its units are kg m^(2) s^(-1). It is not a scalar, but a vactor.
Calculating Angular Momentum of the Earth Strategy No information is given in the statement of the problem; so we must look up pertinent data before we can calculate L = Iω. First, according to Figure 1, the formula for the moment of inertia of a sphere is Figure 1. Some rotational ...
Figure 11.9In three-dimensional space, the position vector→rr→locates a particle in the xy-plane with linear momentum→pp→. The angular momentum with respect to the origin is→l=→r×→pl→=r→×p→, which is in the z-direction. The direction of→ll→is given by the right-hand rul...
The most widely accepted model of Solar System formation, known as the Nebular hypothesis, does not solve the Angular Momentum problem鈥攚hy is the orbital momentum of Jupiter larger than rotational momentum of the Sun? The present manuscript introduces a Rotational Fission model of creation and ...
This 1985 text develops the theory of angular momentum from the viewpoint of a fundamental symmetry in nature and shows how this concept relates to applied areas of research in modern quantum physics. Angular Momentum in Quantum Physics的创作者 ··· James D·Louck 作者 我来说两句 短评 ·...
Angular momentum (Nuclear physicsThis book is concerned with the practical aspects of solving angular momentum problems. The novel but fully tested-out method (the Invariant Graph Method) allows one to write down from a single graph the complete final result of the problem. The drawing of the ...
