Is impulsive tension a real term or just a calculation tool?

[eileen6a]

is it appropriate to call a term impulsive tension or is it just useful for calculation of change of momentum?

 

[dgOnPhys]

usually you call impulsive a force that is non zero for such a short time that it is impractical (or impossible) to measure instant by instant so you have to rely on its impulse that is the change of momentum of what it acts on. For a tension this could be appropriate e.g. an ideal wire is attached to a body and you give it a quick pull and let go of the wire
