Which outcome occurs on a spacecraft accelerating at 1g?

A)Experienced weight matches Earth's gravity
B)Clocks run faster than on Earth
C)Internal temperature approaches absolute zero
D)Inertial mass slowly decreases

💡 Explanation

Because acceleration's effect on spacetime is equivalent to gravity via the equivalence principle, the sensation of 'weight' matches that on Earth given equivalent acceleration; therefore the experienced weight matches Earth gravity, rather than time dilation or phase change effects.
