yes, stretching is a force!
The work done by the stretching body is equal to the difference in potential energy stored in the spring before and after it is stretched. This work is done against the restoring force of the spring.
A stretching force, also known as tension, is a force that elongates or stretches an object. A pulling force is a force exerted on an object to move it towards the direction of the force. Both forces involve pulling or stretching an object.
A stretching force is called tension. It is a force that pulls or elongates an object without changing its shape.
Tension
A stretching force is basically tensile strength. It is measured in pascals or equivalently newtons per square meter. For example, carbon nanotubes have a stretching force or tensile strength of 63 GPa.
The name given to the stretching force that occurs in a spring or rope being pulled is tension. It is a pulling force exerted by the material when it is stretched or pulled.

Ans:opening the fridge(pull)(stretching)
The result of a force moving an object through a distance is called work. Work is calculated by multiplying the force applied to the object by the distance the object moves in the direction of the force.
it is isn't really a force but when something expands, it's called tension.
if the wire experience a change in length (dx), the work(W) is simple equal to: W = F * dx, where F = mg if the wire din experience any lengthen effect, the W will equal to zero due to dx = 0.
