In physics and engineering, kinetics is a term for the branch of classical mechanics that is concerned with the relationship between motion and its causes, namely forces and torques. Since the mid-20th century, the term "dynamics" (or "analytical dynamics") has largely superseded "kinetics" in physics textbooks, though the term is still used in engineering.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.
Biomechanics and kinetics
One of the major components of kinetics is analyzing ones center of pressure. Center of pressure (COP) is often tested using a force plate in a biomechanics lab. Many scientist don't always have access to these expensive and unique equipment. Force plates can be any from thousands to tens of thousands of dollars. Scientist and students today have turned to an alternative way, by using Nintendo Wii Balance Board system as a force plate. One 2014 San Diego State University study has shown a correlation of
The term kinetics is also used to refer to chemical kinetics, particularly in chemical physics and physical chemistry. In such uses, a qualifier is often used or implied, for example: "physical kinetics", "crystal growth kinetics", and so on.
