In this case the "or" does not change the fact that whether the spring is contracting or expanding it still need to be a constant force throughout

And now he's introducing more concepts that he doesn't understand.

Here's a segmented tension system (which, incidentally, looks nothing like a Slinky).

I am wrong.

or absorb movement

It's really not that hard... you're making this into a huge deal

let's break this down slowly.



it must be this. there is no way around that.



typically implying, "not always but usually"



can be, implying it does not need to constantly be pulled or pushed, simply that WHEN it is it dictates that:



when tension is applied it does this.

END OF DEFINITION



used meaning an example or many examples will follow. in this case its saying the most common use is to exert constant tension, such as a car's suspension, but it can also be used to absorb movement, a seperate and entirely different EXAMPLE that fits the DEFINITION.

That is segmented tension used in a roll.

Here's the difference - if you have an object of Length AB and you pull at point a, point b will reflect this change of force because its a constant tension

In a slinky of ab length and you pull on a - the other end is unaffected because all the force is just put into the next coil because it is using segmented tension

but it's absorbing movement.

Try to keep up, please

You're still dodging this:



And what you're trying to define as "segmented tension" (insofar as a Slinky) is a longitudinal wave, not segmented tension.
