← ScienceWhich outcome would validate Einstein’s equivalence principle experientially during freefall?
A)Observer sees only gravitational effects✓
B)Constant proper acceleration is always felt
C)Electrogravitic forces maintain constant levels
D)Inertial mass varies with observer frame
💡 Explanation
The absence of perceived gravity supports equivalence principle because gravitational acceleration and inertial acceleration offsets due to freefall neutralize one another; therefore only inertial effects vanish, rather than differing effects correlating to acceleration.
