Tension is the pulling or stretching force transmitted axially along an object such as a string, rope, chain, rod, truss member, or other object, so as to stretch or pull apart the object. In terms of force, it is the opposite of compression. Tension might also be described as the action-reaction pair of forces acting at each end of an object.
In music, tension is the anticipation music creates in a listener's mind for relaxation or release. For example, tension may be produced through reiteration , increase in dynamic level , gradual motion to a higher or lower pitch , or (partial) syncopations between consonance and dissonance .
An ornamental tone following a principal tone by a skip up or down, usually of a third, and proceeding in the opposite direction by a step, not to be confused with changing tone. canon or kanon (Ger.) A theme that is repeated and imitated and built upon by other instruments with a time delay, creating a layered effect; see Pachelbel's Canon.
Voltage, also known as (electrical) potential difference, electric pressure, or electric tension is the difference in electric potential between two points. [ 1 ] [ 2 ] In a static electric field , it corresponds to the work needed per unit of charge to move a positive test charge from the first point to the second point.
For example, the heart's ventricles contract to expel blood into the pulmonary artery and aorta. As the blood flows out, the previous built-up load is decreased and hence less force is required to expel the rest of the blood. Thus the tension is reduced. [citation needed]
In forming or understanding a word root, one needs a basic comprehension of the terms and the source language.The study of the origin of words is called etymology.For example, if a word was to be formed to indicate a condition of kidneys, there are two primary roots – one from Greek (νεφρός nephr(os)) and one from Latin (ren(es)).
Value-added theory – Professor Neil Smelser (1930-2017) argues that collective behavior is actually a sort of release-valve for built-up tension ("strain") within a social system, community, or group. [5] If the proper determinants are present then collective behavior becomes inevitable.
Zero-length springs are made by manufacturing a coil spring with built-in tension (A twist is introduced into the wire as it is coiled during manufacture; this works because a coiled spring unwinds as it stretches), so if it could contract further, the equilibrium point of the spring, the point at which its restoring force is zero, occurs at a ...
