According to general relativity, what is the physical identity between states of accelerated motion and being at rest in a gravitational field?
- They are opposites
- They are physically identical (correct)
- They are similar but not identical
- They are unrelated
In general relativity, why do objects in free fall move as if no force is exerted on them?
In general relativity, why do objects in free fall move as if no force is exerted on them?
- Because free fall is inertial motion (correct)
- Because of the equivalence principle
- Due to the curvature of spacetime
- Because of the force of gravity
How does general relativity resolve the difficulty of inertially moving objects accelerating with respect to each other?
How does general relativity resolve the difficulty of inertially moving objects accelerating with respect to each other?
- By modifying classical mechanics
- By adopting the principles of special relativity
- By proposing that spacetime is curved (correct)
- By introducing a new force
