TL;DR
In GR terms,
Riding Up-down elevator … during de-acceleration relative to ground and acceleration up…
G force exceeds 1

The same change in velocity relative to ground but at the top of a tower is where G<1

In GR you’re always forced by earth out of your geodesic except if the de-acceleration at the top or acceleration down from the top is made the same as if the elevator fell off the track and was loose

But now with spring/trampoline im reading that the experience at the bottom differs
When “bungee jumping” or trampoline is it correct that the G force would not behave the same on the upward bouncing up due to how the spring stores potential energy or absorbs energy at compression ? Or is your motion up and down when supported by a spring medhanism the same as would be in the elevator motor?

Reading where?

And what does this all have to do with GR?

Sounds like you confused about some basic Newtonian mechanics.

There's your problem. LLMs aren't good at physics.

A lift motor will usually be controlled to minimise discomfort to its passengers. If you bounce off a spring the force is what it is. So a lift will generally smoothly vary the force towards zero as it approaches a stop. A spring will not.

As A.T. says, this has nothing to do with GR.

Ignore anything that AI says regarding physics. We are glad to help you understand valid sources, but AI is not a valid source at this time and it currently generates bad information far faster than we can correct it.

Thread closed.
