- Equilibrium is defined as a state of balance or a stable situation where opposing forces cancel each other out and where no changes are occurring.
- An example of equilibrium is in economics when supply and demand are equal.
- An example of equilibrium is when you are calm and steady.
- An example of equilibrium is when hot air and cold air are entering the room at the same time so that the overall temperature of the room does not change at all.
- a state of balance or equality between opposing forces
- a state of balance or adjustment of conflicting desires, interests, etc.
- the ability of the animal body to keep itself properly oriented or positioned; bodily stability or balance
- mental or emotional stability or balance; poise
- the condition in a reversible chemical reaction in which the products of the reaction are consumed by the reverse reaction at the same rate as they are formed, and there is no net change in the concentrations of the products or the reactants
- the stage of a radioactive material at which the rate of disintegration and the rate of formation are equal for each intermediate product in the radioactive decay series
Origin: Classical Latin aequilibrium ; from aequilibris, evenly balanced ; from aequus (see equal) plush libra, a balance

noun pl. e·qui·lib·ri·ums or e·qui·lib·ri·a
- A condition in which all acting influences are canceled by others, resulting in a stable, balanced, or unchanging system.
- Mental or emotional balance; poise.
- Physics The state of a body or physical system at rest or in unaccelerated motion in which the resultant of all forces acting on it is zero and the sum of all torques about any axis is zero.
- Chemistry The state of a chemical reaction in which its forward and reverse reactions occur at equal rates so that the concentration of the reactants and products does not change with time.
Origin: Latin aequilībrium : aequi-, equi- + lībra, balance.
equilibrium - Business Definition
equilibrium - Cultural Definition
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.)
In 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.
- Keynesian economics departed from conventional economic theory in demonstrating that economic equilibrium and full employment need not occur together. Therefore, as a system tends toward equilibrium, it might not eliminate unemployment.
equilibrium - Medical Definition
- A condition in which all influences acting upon it are canceled by others, resulting in a stable, balanced, or unchanging system.
- The state of a chemical reaction in which its forward and reverse reactions occur at equal rates so that the concentration of the reactants and products does not change with time. Also called dynamic equilibrium.
- Mental or emotional balance.
equilibrium - Science Definition
Plural equilibriums equilibriums or 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.
