The Equivalence Principle: Unraveling the Connection between Gravity and Acceleration

Question 1

According to the Equivalence Principle, if you're inside a spaceship moving at a constant speed, does it feel like you're in a gravitational field?

Accepted Answer

Yes, because the Equivalence Principle says constant acceleration is the same as gravity.

Answer

No, because the spaceship isn't in a gravitational field.

Answer

Yes, but only when the spaceship speeds up towards Earth.

Answer

No, because you can't feel gravity inside a spaceship.
