20世纪一来，前者基本取代了后者
In physics and engineering, kinetics is a term for the branch of classical mechanics that is concerned with the relationship between the motion of bodies and its causes, namely forces and mass.[1][2][3] Since the mid-20th century, the term "dynamics" (or "analytical dynamics") has largely superseded "kinetics" in physics text books[4]; the term "kinetics" is still used in engineering. For example, according to Rao et al.:[5]

The relation between the external forces and their kinematic variables is popularly known as kinetics. … We examine the external mechanical agencies that cause the motion.…The motion of a rigid body consists of rigid translations as well as rotations. Each of these kinematic variables will now have to be related to their respective kinetic variables. The kinetic quantities associated with translations are forces and the kinetic quantities associated with rotations are moments or torques.

– Rao, Lakshminarasimhan, Sethuraman & Sivakumar , Engineering Mechanics: Statics and Dynamics (2003), p. 175

The term kinetics is also used in a sense akin to chemical kinetics, particularly in chemical physics and physical chemistry.[6][7][8][9][10] In such uses, a qualifier is often used or implied, for example: "physical kinetics", "crystal growth kinetics", and so on.



以上根据wiki

kinetics的counterpart是statics，静[止]力学，分析静止物体的受力，

第一个就是通常所说的动力学，第二个可以理解成动理学，主要研究处于非统计平衡的系统的微观过程~比如说对非平衡气体的含时速度分布以及借助这一分布进行的对其粘度，热导率等的研究就属于knetics的范畴
