A Demonstration of Einstein's Equivalence of Gravity and Acceleration
Newburgh, Ronald
European Journal of Physics, v29 n2 p209-214 Mar 2008
In 1907, Einstein described a "Gedankenexperiment" in which he showed that free fall in a gravitational field is indistinguishable from a body at rest in an elevator accelerated upwards in zero gravity. This paper describes an apparatus, which is simple to make and simple to operate, that acts as an observable footnote to Einstein's example. It also includes an examination of acceleration-dependent forces as well as a discussion of those frames of reference in which Newton's laws of classical mechanics are not valid. (Contains 1 figure.)
