Classical mechanics |

In physics and engineering, kinetics is the branch of classical mechanics that is concerned with the relationship between the motion and its causes, specifically, forces and torques. [1] [2] [3] Since the mid-20th century, the term " dynamics" (or "analytical dynamics") has largely superseded "kinetics" in physics textbooks, [4] though the term is still used in engineering.
In plasma physics, kinetics refers to the study of continua in velocity space. This is usually in the context of non-thermal ( non-Maxwellian) velocity distributions, or processes that perturb thermal distributions. These " kinetic plasmas" cannot be adequately described with fluid equations.
The term kinetics is also used to refer to chemical kinetics, particularly in chemical physics and physical chemistry. [5] [6] [7] [8] [9] In such uses, a qualifier is often used or implied, for example: "physical kinetics", "crystal growth kinetics", and so on.
