Detailed explanation-1: -– Equivalence principle states that “inertial force and gravitational force are the same thing.” – Or, “acceleration and gravity are the same thing.”
Detailed explanation-2: -In an accelerating frame, the equivalence principle tells us that measurements will come out the same as if there were a gravitational field. But if the spacetime is flat, describing it in an accelerating frame doesn’t make it curved.
Detailed explanation-3: -What is the equivalence principle? The equivalence principle is the fundamental law in modern physics, which describes that inertial and gravitational forces are similar in nature and usually indistinguishable.
Detailed explanation-4: -Between 1911 and 1915, Einstein developed the idea that gravitation is equivalent to acceleration, initially stated as the equivalence principle, into his general theory of relativity, which fuses the three dimensions of space and the one dimension of time into the four-dimensional fabric of spacetime.
