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.
When the forces are collinear (aligned with each other), they are called tension forces or compression forces. Shear force can also be defined in terms of planes : "If a plane is passed through a body, a force acting along this plane is called a shear force or shearing force ."
In physics, magnetic tension is a restoring force with units of force density that acts to straighten bent magnetic field lines. In SI units, the force density f T {\displaystyle \mathbf {f} _{T}} exerted perpendicular to a magnetic field B {\displaystyle \mathbf {B} } can be expressed as
Tension (physics), a force related to the stretching of an object (the opposite of compression) Tension (geology) , a stress which stretches rocks in two opposite directions Voltage or electric tension, the difference in electric potential energy between two points
Nonconservative forces other than friction include other contact forces, tension, compression, and drag. For any sufficiently detailed description, all these forces are the results of conservative ones since each of these macroscopic forces are the net results of the gradients of microscopic potentials.

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.
A chain hanging from points forms a catenary. The silk on a spider's web forming multiple elastic catenaries.. In physics and geometry, a catenary (US: / ˈ k æ t ən ɛr i / KAT-ən-err-ee, UK: / k ə ˈ t iː n ər i / kə-TEE-nər-ee) is the curve that an idealized hanging chain or cable assumes under its own weight when supported only at its ends in a uniform gravitational field.
An equation for the acceleration can be derived by analyzing forces. Assuming a massless, inextensible string and an ideal massless pulley, the only forces to consider are: tension force (T), and the weight of the two masses (W 1 and W 2). To find an acceleration, consider the forces affecting each individual mass.
