← ScienceWhich outcome arises on a spacecraft due to frame equivalence?
A)Weight and acceleration become indistinguishable✓
B)Constant velocity mirrors gravitational deceleration
C)Electromagnetic damping matches viscous drag
D)Optical aberration imitates inertial dampening
💡 Explanation
The equivalence principle states a gravitational field is equivalent to acceleration; therefore an astronaut cannot distinguish between gravity pulling on their body and the spacecraft accelerating, because gravity's effects mimic acceleration rather than only velocity changes.
