angular momentum vector 中文意思是什麼
angular momentum vector
解釋
角動量向量-
Angular momentum is an axial vector quantity.
角動量是一種軸矢量。 -
If the wheel is rotating counterclockwise, its angular-momentum vector is directed eastward.
如果輪子是逆時針方向旋轉,其角動量矢量的方向朝東。 -
Orbital angular momentum vector
軌道角動量矢量 -
In the motion, the direction of angular momentum vector changes every moment, because there is a torque caused by gravity act on the wheel, then the wheel rotate itself and rotate around the fixed point
車輪進動實驗:在進動中,角動量的矢量方向不斷改變,是因為受到一個由重力產生的力矩,使車輪在自轉的同時又繞支點轉動。 -
In some ways, an electron is just like such a spinning sphere of charge ? an electron has a quantity of angular momentum ( its “ spin ” ) and an associated magnetism, and in an ambient magnetic field its energy depends on how its spin vector is oriented
就某種意義而言,電子可類比於一個旋轉的帶電小球:它帶有角動量(就是自旋)以及伴隨而來的磁性,而它的能量是由自旋向量與外加磁場的關系來決定。
