Discussion Overview

The discussion centers around the differences in G-forces experienced during bungee jumping or bouncing on a trampoline compared to those experienced in an elevator. Participants explore the mechanics of how springs store and release energy, and how this might affect the experience of G-forces in different scenarios.

Discussion Character

  • Debate/contested, Conceptual clarification, Technical explanation

Main Points Raised

  • Some participants propose that the G-forces experienced during upward and downward motion on a spring mechanism differ from those in an elevator due to the way springs store potential energy and absorb energy at compression.
  • Others argue that the experience at the bottom of a bounce differs from that in an elevator, suggesting a need for clarification on the mechanics involved.
  • A participant mentions that elevator motors are typically controlled to minimize discomfort, implying that the forces experienced in an elevator are managed differently than those from a spring.
  • There is a suggestion that the discussion may be conflating concepts from general relativity (GR) with Newtonian mechanics, with some participants expressing confusion about the relevance of GR to the topic.
  • One participant emphasizes that AI-generated information is not reliable for understanding physics, suggesting that it may lead to misunderstandings.

Areas of Agreement / Disagreement

Participants express disagreement regarding the comparison of G-forces in different scenarios, with some asserting that the experiences differ significantly while others question the relevance of certain claims. The discussion remains unresolved with multiple competing views present.

Contextual Notes

There are indications of confusion regarding the application of Newtonian mechanics versus general relativity, as well as the reliability of AI-generated information in the context of physics discussions.

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.

Read a physics book instead.

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.
