The branch of mechanics concerned purely with the motion of bodies. This is in contrast to dynamics, which also considers the reasons for motion, e.g. the forces acting on such bodies
the body of knowledge that deals with the effects of forces that produce or modify body motion
As applied to ion channels kinetics usually encompasses the study of rate of change ion channels undergo during gating, ion passage, etc Kinetics is often used in order to uncover specific "mechanisms" channels undergo when changing from one state to another and to explain the phenomena of gating, "jumps", "bursts", "transition times", sub-conductance modes, ligand interactions, etc Complex mathematical treatments involving the kinetics of ion channels have been undertaken in order to gain insight into how ion channels accomplish this
Kinetics is the science of measuring changes, of assessing rates of movements and flow In biology, kinetics is concerned with enzyme kinetics, the rate of how proteins help catalyze a chemical reactions Another application of kinetics is the rate of flow of molecules in solution by diffusion or in an energy field (such as charges in an electric field, or mass in a gravitational field) Flux rates of molecules across biological membranes are also studied by kinetics
The study of the relationship between motion and the forces affecting motion; bodies changing motion as unbalanced forces act on them The concepts of mass, force, and energy as they affect motion
