← ScienceWhich outcome occurs because gravitational mass is equivalent to inertal mass in a freefalling satellite?
A)Apparent weightlessness experienced by its occupants✓
B)Increased structural stress on satellite components
C)Gravitational redshifting of communications signal
D)Decreased oxidation rates of external surfaces
💡 Explanation
Apparent weightlessness occurs because equal gravitational and inertial mass means gravitational acceleration is indistinguishable from acceleration of the frame. The equivalence principle causes the sensation of weight to vanish; therefore astronauts float, rather than feeling increased stress on components.
