angular momentum vector 中文意思是什麼

angular momentum vector 解釋
角動量向量
  • angular : adj. 1. 有角的,角形的;尖銳的。2. 用角度量的;角的。3. 瘦骨嶙峋的。4. 不靈活的,生硬的。adv. -ly
  • momentum : n. (pl. momentums, -ta ) 【物理學】動量;【火箭】總沖量;〈口語〉惰性;勢頭;要素,契機。 the momentum of attack 進攻的銳氣[頸頭]。
  • vector : n 1 【數學】向量,矢量,動徑。2 【航空】飛機航線;航向指示。3 【天文學】幅,矢徑。4 【生物學】帶...
  1. Angular momentum is an axial vector quantity.

    角動量是一種軸矢量。
  2. 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。
  3. Orbital angular momentum vector

    軌道角動量矢量
  4. 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。
  5. 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。
