← ScienceWhich outcome occurs when gravity's influence matches inertia's effect?
A)No effective forces are experienced✓
B)Internal stresses within object increase
C)Object's thermal expansion accelerates rapidly
D)Doppler shift causes emitted light-bending
💡 Explanation
An object experiences weightlessness because gravity and acceleration become indistinguishable according to Einstein's equivalence principle; The inertial frame cancels gravitational effects, therefore A is right rather than B, C, D because the acceleration is balanced.
