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.
