※ 引述《JGU (ROYGBIV)》之铭言： : 这三个字都是力学 : 代表的意思有什麽差别啊? dynamics,kinetics,mechanics Mechanics is a branch of the physical sciences that is concerned with the state of rest or motion of bodies subjected to the action of forces. The mechanics of righd bodies is divided into two areas:statics and dynamics. Statics is concerned with the equilbrium of a body that is either at rest or moves with constant velocity. The foregoing treatment is concerned with dynamics which deals with the accelerated motion of a body. Here the subject of dynamics will be presented in two parts: Kinematics, which treats only the geometric aspects of the motion, and Kinetics, which is the analysis of the forces causing the motion. From R.C Hibbler Engineering Mechanics Dynamics, P3-Introduction. As this result, we can defind a branch-diagram for yours question: Electronics, Thermodynamics, Electromagnetics, Optics ↗ Physics-->Mechanics-->Statics ↘ Dynamics-->Kinematics ↘ Kinetics ※ 编辑: harry901 来自: 59.117.132.207 (01/04 14:26)
