摘要
两体系统的功能原理与机械能守恒是正确理解和解决某些实际力学问题的基础.文中分析了惯性参照系、质心参照系及相对参照系中两体系统的功能原理与机械能守恒,并结合具体的应用给出结论.
The principle of work-energy and the law of conservation of mechanical energy in two-body system is the base of understanding and solving some practical problems.The paper gives some analysis and useful discussion about theorem of kinetic energy and law of conservation of mechanical energy in two-body system in inertial system or center-of-mass system or relative reference system.At last,this paper gives some samples and some conclusions.
