Einstein's Equivalence Principle Put to Test, Discovery News | 5/6/16 An orbital experiment is about to test to see if objects really fall at same speed in a gravitational field — or wither some exotic physics may be detected.
Equivalence Principle: In this video Paul Andersen explains how inertial mass and gravitational mass are equivalent. He shows you too simple methods for calculated individual inertial mass and gravitational mass. Albert Einstein used this principle to build his general theory of relativity.
During ten seconds of weightlessness Brynle Barrett from the Laboratory of Photonics, Numerical Sciences and Nanosciences at the University of Bordeaux monitors an experiment to test the ‘weak equivalence principle’ – or why a feather in a vacuum falls as fast as a hammer.
