The Principle of Equivalence: Demonstrations of Local Effective Vertical and Horizontal
Munera, Hector A.
Physics Teacher, v48 n2 p131-133 Feb 2010
It has been suggested that Einstein's principle of equivalence (PE) should be introduced at an early stage. This principle leads to the notion of local effective gravity, which in turn defines effective vertical and horizontal directions. Local effective gravity need not coincide with the direction of terrestrial gravity. This paper describes three classroom demonstrations that we have used to teach the concepts of the effective horizontal plane and the effective vertical direction to students at National University in Bogota.
