The Equivalence Principle assumes a constant 1g acceleration:
“ Another clarification needed is that the equivalence principle assumes a constant acceleration of 1g without considering the mechanics of generating 1g. ”
Johannes Fankhauser at the University of Oxford says:
“ Einstein’s equivalence principle (also called the weak equivalence principle) assumes that any experiment in a uniform gravitational field yields the same results as the analogous experiment performed in a frame removed from any source of gravitational field but moving in uniform accelerated motion with respect to an inertial frame [Norton, 1985].3 ”
Physicists also often assume a uniform gravitational field. Professor Vincent Buonomano at the State University of Campinas states:
“ We always assume a uniform gravitational intensity unless stated otherwise. ”
Searching for Extra Dimensions
From the introduction of Searching for Extra Dimensions and New String-Inspired Forces in the Casimir Regime (Archive), its authors Dr. Dennis E. Krause (bio) and Physics Professor Ephraim Fischbach (bio) tell us:
“ When Isaac Newton formulated his law of universal gravity over 300 years ago, he provided the first mathematical description of one of the fundamental forces of nature. Yet, physicists have realized only relatively recently that tests of Newtonian gravity can still provide a unique window into new physics [1-7]. Within the past 20 years, experimentalists have put Newtonian gravity to the test for distance scales 10-3-1015 m by searching for violations of the weak equivalence principle (WEP) and inverse square law (ISL). The fact that no such violations have been observed places stringent constraints on extensions of the Standard Model that would naturally lead to such effects [1]. ”
