angular motion vector 中文意思是什麼
angular motion vector
解釋
角運動向量-
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。
