Question

Quizplus · Accepted Answer

The equivalence principle, a key concept in Einstein's theory of general relativity, states that the effects of gravity are indistinguishable from the effects of acceleration. A person riding in an elevator, especially when it starts or stops moving, experiences forces similar to those caused by gravity, making it a classic illustration of this principle.
