Tension may mean:

• In physics, tension is a force related to the stretching of a string or a similar object. See Tension (mechanics).

More generally, tension can be defined as a positive normal stress acting on a body. A stress is defined as a force acting on a surface. In the International System, it is measured in Pascals (Pa)(1Pa=1N/m²). The stress is a tensor, having nine components (3x3). The components in the diagonal of the tensor are the normal stresses. The word "tension" typically refers to any of these three quantities provided that they have a positive value. The word "compression" is use in the case of having negative normal stresses. It should be stressed that the words "Tension", "compression" and stress" refers to forces acting on surfaces. And example of this is the atmospheric pressure.

• The word 'tension' is also sometimes used to refer to electrical voltage; this is the usage in the term high-tension line.

• Colloquially, 'tension' is used to refer to physiological or mental stress.

• In music tension is the perceived need for relaxation or release (Sturm und Drang) created by a listener's expectations as well as dissonance, repetition, tempo, a gradual rise in pitch, and other factors.

• In phonetics, tenseness describes a certain sound quality.

• In film, Tension is a 1950 film noir.
