We are interested in determining the amount of linear momentum delivered to the electron by the field . 我們對確定場傳遞給電子的線性動量的大小感興趣。
In other words, the vertical component of its linear momentum remains zero, since there is no resultant vertical force . 換句話說,因為沒有豎直方向的合力,所以線動量的豎直方向仍為零。
Principle of linear momentum 線性動量定理
This should obviously violate the laws of conservation of linear momentum and energy 很顯然,這違反了線性動量和能量守恒定律。
In motions of rotation angular momentum appears in much the same way as linear momentum appears in motion of translation 在旋轉運動中的角動量產生的方式與平移運動中的線動量的產生是基本相似的。
