- Dynamics (physics)
In physics the term

**dynamics**customarily refers to the time evolution of physical processes. These processes may be microscopic as inparticle physics ,kinetic theory , andchemical reactions ,cite book |title=Theories of Molecular Reaction Dynamics: The Microscopic Foundation of Chemical Kinetics |author=Niels E.
