← ScienceWhich outcome results when assuming inertial-gravitational 'equivalence' in a local setting containing a freely-falling elevator?
A)Acceleration mimics gravitational field effects✓
B)Spacetime curvature affects the observer
C)Internal relative potential energy varies
D)Mass and density gradients are altered
💡 Explanation
Acceleration mimics gravitational effects because Einstein's equivalence principle posits their indistinguishability; therefore, an observer within the elevator perceives effects identical to gravity, rather than detecting spacetime curvature directly or measuring potential energy differences in a globally static environment.
