Science definitions for equilibrium Plural equilibriums equilibria Physics The state of a body or physical system that is at rest or in constant and unchanging motion. A system that is in equilibrium shows no tendency to alter over time. ♦ If a system is in static equilibrium, there are no net forces and no net torque in the system. ♦ If a system is in stable equilibrium, small disturbances to the system cause only a temporary change before it returns to its original state. Chemistry The state of a reversible chemical reaction in which its forward and reverse reactions occur at equal rates so that the concentration of the reactants and products remains the same.

Culture definitions for equilibrium
economics, a state of the economy in which for every commodity or service (including labor), total supply and demand are exactly equal. Equilibrium is never actually attained; it is approximated by movements of the market. Note Keynesian
economics departed from conventional economic
in demonstrating that economic equilibrium and
need not occur together. Therefore, as a system tends toward equilibrium, it might not eliminate unemployment.
A condition in which all influences acting cancel each other, so that a static or balanced situation results. In
physics, equilibrium results from the cancellation of forces acting on an object. In chemistry, it occurs when chemical reactions are proceeding in such a way that the amount of each substance in a system remains the same. ( See chemical equilibrium.)
