Please add the URL of the simulation when you ask question related to that simulation.

To simplify the problem, we ignore the mass of the spring when deal with spring and mass.
i.e. it means that the mass of the attached particle is much larger than the mass of the spring.

For a falling slinky, the whole spring is divided into many small spring, each has to support the mass of the springs below itself.
