kinetics

The branch of chemistry that is concerned with the rates of change in the concentration of reactants in a chemical reaction.

That branch of the science of dynamics which treats of forces causing or changing the motion in bodies or of the circumstances of actual motion: opposed to statics, and synonymous with dynamics in one of the senses of that word. See dynamics.

See dynamics.

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 branch of chemistry that is concerned with the rates of chemical reactions.
