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namely forces and mass.¹²³ Since the mid-20th century, the term "dynamics" (or "analytical dynamics") has largely superseded "kinetics" in physics text books⁴; the term "kinetics" is still used in engineering.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.⁶⁷⁸⁹¹⁰ In such uses, a qualifier is often used or implied, for example: "physical kinetics", "crystal growth kinetics", and so on.
