← ScienceWhich effect confirms the equivalence principle during freefall?
A)Objects' acceleration feels indistinguishable from gravity✓
B)Gravity abruptly vanishes for nearby objects
C)Increased radiation emissions become imperceptible
D)Frame dragging stops relative to external observers
💡 Explanation
Objects in freefall experience weightlessness because gravitational effects are locally equivalent to acceleration, demonstrating Einstein's equivalence principle; therefore, this feeling cancels out, rather than causing changes in radiation or spacetime itself.
