The principle of equivalence states that observations made in an accelerating reference frame are indistinguishable from those made in a gravitational field, providing a link between the geometric theory of gravity (general relativity) and the theory of motion (classical mechanics). It does not relate mass and energy, space and time, or electricity and magnetism in the same way.
