What is another word for principle of equivalence?
Pronunciation: [pɹˈɪnsɪpə͡l ɒv ɪkwˈɪvələns] (IPA) 
The principle of equivalence is a fundamental concept in physics that links the effects of gravity to a uniform acceleration. Synonyms for this idea include the equivalence principle, the Einstein equivalence principle, and the strong equivalence principle. These terms refer to the same central concept within physics but may be used in different contexts or colloquially. The principle of equivalence is important in understanding the behavior of objects in a gravitational field and underpins many of the fundamental predictions of general relativity. Understanding the different ways this principle can be expressed can help deepen one's understanding of physics and the laws governing the physical world.
