← ScienceWhich phenomenon allows accurate inertial navigation, even around curves?
A)Equivalence principle masking gravitational forces✓
B)Coriolis effect predicting curved paths
C)Doppler shift estimating relative velocity
D)Quantum entanglement instantaneous data transfer
💡 Explanation
Navigation requires precise acceleration measurement; the equivalence principle states gravitational acceleration cannot be distinguished from inertial acceleration, therefore a sensor in freefall measures only navigation forces, rather than net gravity and inertial force.
