GR perplexity for a layman



In GR acceleration is equivalent to gravity, vis a vis the
gedanken(sp?) experiment man in an elevator. My perplexity is
acceleration acts equally over the entire elevator while gravity is
1/R^2 so that the gravitional force at the top of the man is different
from his feet. Will someone please set me straight on this.

Thanks

  • Re: The Principle of Equivalence Explained
    ... Consider an observer in a freely falling elevator, objects released from rest relative to the elevator cabin remain floating 'weightless' in the cabin. ... In another words, gravitational mass and inertial mass is equal, this is the famous principle called the Weak Equivalence Principle or WEP. ... If we consider the elevator cabin over a short time period and that it is spatially small, then a freely falling elevator resembles a Cartesian inertial frame of reference, the laws of special relativity hold inside the elevator. ... We thus see that WEP states that since it is impossible to detect gravity from local region, one could came with an idea that local laws of physics reduces to special relativity. ...
