| 摘 要： | 刚体的运动分为平动和转动,那么刚体的动能也就包括平动动能和转动动能。在建立惯性坐标系和运动坐标系的基础上,以动能的定义式为出发点,对刚体的动能进行剖析,并讨论了刚体纯滚动情况下的动能,得到了相关的结论。

| Abstract: | The motion of a rigid body can be divided into two types: translation and rotation,so the kinetic energy of rigid body is made up of translational energy and rotational energy.In this paper, starting from the definition of kinetic energy,and by establishing the inertial frame and the reference frame,we have a discussion of the kinetic energy of rigid body and get some conclusions on kinetic energy of rigid body simply in rotation. |

| Keywords: | rigid body reference frame translational energy rotational energy |
