← ScienceWhich effect occurs when comparing gravitational and inertial mass?
A)Gravitational lensing of distant stars
B)Accelerating frames yield equivalent effects✓
C)Inertial frames cause black hole formation
D)Mass loses its ability to curve spacetime
💡 Explanation
An accelerating frame of reference is locally indistinguishable from a gravitational field because of the Einstein equivalence principle; therefore an astronaut cannot tell if they are accelerating or simply experiencing gravity, rather than other phenomena arising only from gravity or inertia.
