contraction,

in physics: see expansionexpansion,
in physics, increase in volume resulting from an increase in temperature. Contraction is the reverse process. When heat is applied to a body, the rate of vibration and the distances between the molecules composing it are increased and, hence, the space occupied by the

contraction,

in writing: see abbreviationabbreviation,
in writing, arbitrary shortening of a word, usually by cutting off letters from the end, as in U.S. and Gen. (General). Contraction serves the same purpose but is understood strictly to be the shortening of a word by cutting out letters in the middle, the omission

(graphic arts)
A microfilm defect in the form of a compressed image that occurs when the film speed is reduced as the document passes through a rotary microfilmer.
(mathematics)
A function f from a metric space to itself for which there is a constant K that is less than 1 such that, for any two elements in the space, a and b, the distance between f (a) and f (b) is less than K times the distance between a and b.

The action or process of becoming smaller or pressed together, as a gas on cooling.

Results are consistent with the classical inverse relationship between torque (force) and velocity in that both PT and AVT were greatest when tested isometrically, followed by dynamic contractions at 500, 1000, 2000, and 4000 s-1 (Table 1).
