This motion can be used to run a lathe or some other machine. 這種旋轉運動可用來開動車床或其他機器。
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。
Similar cyclic stresses may have occurred due to wind-induced swaying motion during storage. 同樣在存放時由風力引起的橫向擺動也可以產生類似的循環應力。
Impulsion may be recognized by the freely swinging back and the participation of all the joints in the forward motion. 自由擺動的背部和身體所有關節都參與向前的運動是動力的表現。
