Definition of Kinetic

Kinetic: With movement. The opposite of kinetic is akinetic. It means without movement. In neurology, kinetic and akinetic denote the presence or absence of movement. Kinetic comes from the Greek word "kinesis" for motion. The term "akinetic" is put together from the prefix "a-" meaning "without" + "kinesis" = without motion. "Kinetic" (an adjective) should be distinguished from "kinetics" (a noun). Kinetics (with an "s" at the end) refers to the rate of change in a biochemical (or other) reaction, the study of reaction rates.
