摘要
通过质心运动定律和绕质心的转动定律得到刚体非定轴转动的动能定理,并对两道力学习题作了分析和讨论。
By the law of kinematic of centre - mass and the fundamental law of dynamics of rotational motion about the axis through the center of mass it achieves the theorem of kinetic energy of rigid body with non - fixed axis through the center, and it analyses and discusses the two exercises of mechanics.
