I understand the mechanism of simulating a spring or a system of springs. However, what assumptions do we have to make before the simulation? For instance, the fixpoint of the spring should not be considered as movable (even though the material for it may have a very very small k value). Also, in our simulation, how can we determine if an object should be considered as part of the spring system or not? To what scale or under what conditions should the object be considered with a k value?

I think anything other than a perfect rigid body can be considered as a spring but with different k coeff. For example, a cloth can be a spring with very high k (they can be stretched a little but not that much)
