相对质心的动力学定理

Dynamic Theorem on Relative to the Center of Mass

摘要: 本文研究了质点系相对质心的动力学问题,推证了相对质心的动量定理和动能定理,并通过例题阐述了它们的应用,最后结合已有的相对于质心的动量矩定理,总结了相对于质心的动力学定理的理论意义及其应用方法和范围.

Abstract: This paper has studied the dynamic problem of the system relative to center of mass. The theorems of momentum and kinetic energy relative to the Center of mass are prerented and proved in the paper The application of these theorems are also discussed finally theoretical meaning and application range of the theorems is generaliged.
