Title: Ask

Hello Prof  :)
My ask about Falling Slinky Model I'm try understand what simulation explain
I mean no have mass for to be have force to make model falling so like for example
Another model is Falling Cup with ball Model OK we have fall because have a ball so
We have force but in first simulation falling slinky no have ball so why falling  ???
Waiting answer
Respect
Ahmed

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.
