dynamic equilibrium[dī¦nam·ik ē·kwə′lib·rē·əm] Also known as kinetic equilibrium. (mechanics) The condition of any mechanical system when the kinetic reaction is regarded as a force, so that the resultant force on the system is zero according to d'Alembert's principle. (physics) A condition in which several processes act simultaneously to maintain a system in an overall state that does not change with time. dynamic equilibrium
equilibrium [e″kwĭ-lib´re-um] 1. harmonious adjustment of different elements or parts; called also balance.2. a state of chemical balance in the body, reached when the tissues contain the proper proportions of various salts and water. See also acid-base balance and fluid balance.3. sense of equilibrium.dynamic equilibrium the condition of balance between varying, shifting, and opposing forces that is characteristic of living processes.e·qui·lib·ri·um (ē'kwi-lib'rē-ŭm), 1. The condition of being evenly balanced; a state of repose between two or more antagonistic forces that exactly counteract each other.
See also: equilibrium constant. 2. In chemistry, a state of apparent repose created by two reactions proceeding in opposite directions at equal speed; in chemical equations, sometimes indicated by two opposing arrows (⇄) instead of the equal sign.
See also: equilibrium constant. Synonym(s): dynamic equilibrium [L. aequilibrium, a horizontal position, fr. aequus, equal, + libra, a balance] e·qui·lib·ri·um (ē'kwi-lib'rē-ŭm) 1. The condition of being evenly balanced; a state of repose between two or more antagonistic forces that exactly counteract each other. 2. chemistry A state of apparent repose created by two reactions proceeding in opposite directions at equal speed; in chemical equations, sometimes indicated by two opposing arrows (↔) or (⇌).
Synonym(s): dynamic equilibrium. [L. aequilibrium, a horizontal position, fr. aequus, equal, + libra, a balance]dynamic equilibrium the apparently steady but actually fluctuating state which is exhibited by stable ecosystems and communities. fluctuations occur within such systems in relation to seasons, life cycles, nutrient cycles, energy cycles, successional stages etc., all within an apparently stable system. Changes thus occur all the time within such a system, even in a so-called climax community, though these changes are usually small so that such systems are said to be ‘stable’ even though they are in fact in a state of constant change.FinancialSeeEquilibrium |
