Elasticity often refers to:

Elasticity (physics)
In physics and materials science, elasticity is the ability of a body to resist a distorting influence and to return to its original size and shape when that influence or force is removed. Solid objects will deform when adequate loads are a ...
, continuum mechanics of bodies that deform reversibly under stress
Elasticity may also refer to:
Information technology
*
Elasticity (data store) The elasticity of a data store relates to the flexibility of its data model and clustering capabilities. The greater the number of data model changes that can be tolerated, and the more easily the clustering can be managed, the more elastic the dat ...
, the flexibility of the data model and the clustering
*
Elasticity (system resource)
In computing, elasticity is defined as "the degree to which a system is able to adapt to workload changes by provisioning and de-provisioning resources in an autonomic manner, such that at each point in time the available resources match the cur ...
, a defining feature of distributed system
Economics
Elasticity (economics)
In economics, elasticity measures the responsiveness of one economic variable to a change in another. For example, if the price elasticity of the demand of a good is −2, then a 10% increase in price will cause the quantity demanded to fall by 2 ...
, a general term for a ratio of change. For more specific economic forms of elasticity, see:
*
Cross elasticity of demand
In economics, the cross (or cross-price) elasticity of demand (XED) measures the effect of changes in the price of one good on the quantity demanded of another good. This reflects the fact that the quantity demanded of good is dependent on not on ...
*
Elasticity of substitution
Elasticity of substitution is the ratio of percentage change in capital-labour ratio with the percentage change in Marginal Rate of Technical Substitution. In a competitive market, it measures the percentage change in the two inputs used in respon ...
*
Frisch elasticity of labor supply
The Frisch elasticity of labor supply captures the elasticity of hours worked to the wage rate, given a constant marginal utility of wealth. Marginal utility is constant for risk-neutral individuals according to microeconomics. In other words, th ...
*
Income elasticity of demand
In economics, the income elasticity of demand (YED) is the responsivenesses of the quantity demanded for a good to a change in consumer income. It is measured as the ratio of the percentage change in quantity demanded to the percentage change in ...
*
Output elasticity
In economics, output elasticity is the percentage change of output ( GDP or production of a single firm) divided by the percentage change of an input. It is sometimes called ''partial output elasticity'' to clarify that it refers to the change of o ...
*
Price elasticity of demand
A good's price elasticity of demand (E_d, PED) is a measure of how sensitive the quantity demanded is to its price. When the price rises, quantity demanded falls for almost any good ( law of demand), but it falls more for some than for others. Th ...
*
Price elasticity of supply
The price elasticity of supply (PES or Es) is commonly known as “a measure used in economics to show the responsiveness, or elasticity, of the quantity supplied of a good or service to a change in its price.” Price elasticity of supply, in ...
*
Yield elasticity of bond value
The yield elasticity of bond value is the elasticity of the market value of a bond with respect to its yield—the percentage change in bond value divided by its causative percent change in the yield to maturity of the bond. Equivalently, it is ...

Elasticity of a function In mathematics, the elasticity or point elasticity of a positive differentiable function ''f'' of a positive variable (positive input, positive output) at point ''a'' is defined as
:Ef(a) = \fracf'(a)
:=\lim_\frac\frac=\lim_\frac\frac=\lim_\frac\ap ...
, a mathematical definition of point elasticity
*
Arc elasticity In mathematics and economics, the arc elasticity is the elasticity of one variable with respect to another between two given points. It is the ratio of the percentage change of one of the variables between the two points to the percentage change of ...

Elasticity coefficient
In chemistry, the Reaction rate, rate of a chemical reaction is influenced by many different factors, such as temperature, pH, reactant, the concentration of Product (chemistry), products, and other effectors. The degree to which these factors c ...
