← ScienceWhich mechanism causes differential gravitational acceleration within an object?
A)Tidal force stretching exceeds material strength✓
B)Frame dragging distorts spacetime locality
C)Quantum entanglement affects paired particles
D)Expansion rate increases cosmological spacing
💡 Explanation
Gravitational fields vary with distance; therefore differential pull results in tidal force stretching, because regions closer to the mass experience greater acceleration. Thus, if this exceeds material strength, the object distorts, rather than frame dragging or expansion applying primarily at this scale.
