摘要
本文根据在非惯性系中的动力学定律推导出非惯性系中质点的角动量定理和非惯性系中质点组的角动量定理,并举例说明应用这定理解题会更为便利,有些问题若选用质心坐标系,用这定理解题可避免复杂的运算,使求解更加简便.
Angular momentum, laws of both the particle and the particles group in non-iaertial system have been deduced by means of dynamic law in non-inertial system. Examples are given to show that it is more convenient to solve problems by these laws and that it is easier and simpler to workout solutions especially by the laws in center of mass coordinates.
