A state of rest defined by Newton's second law.

the point at which quantity demanded and quantity supplied are equal at a particular price

equality of distribution

A situation in which there is no tendency for change. For example, an equilibrium price is a price that can be maintained.

A price level in a sideways market equal-distance from the resistance and support levels.

In a market, equilibrium is the point at which the quantity supplied of a good or service equals the quantity demanded. Markets tend to move toward equilibrium as a consequence of the fact that people seek to satisfy their desires with the least exertion. Equilibrium is a characteristic of any kind of market, whether individual or aggregate.

The amount of output supplied equals the amount demanded. At equilibrium, the market has neither a tendency to rise nor fall but clears at the existing price.

Equilibrium means "at rest" -- a state or outcome for which there is no tendency for the system to deviate. The term equilibrium is used in many ways in economics. Market equilibrium is the price-quantity combination in a market from which there is no tendency for buyers or sellers to move away. Graphically, market equilibrium is the intersection point of the supply curve and the demand curve. At market equilibrium, there is a price at which quantity demanded is exactly equal to quantity supplied; therefore, there is neither a shortage nor surplus. Consumer equilibrium is the condition where the consumer is consuming their utility-maximizing bundle of products, given their budget constraint and the prices paid for the products. At this point, there is no motivation for the consumer to change his or her consumption of products. This occurs where the marginal utility per dollar spent on each product equal for all products purchased.
