- A.The laws of physics are the same in all inertial frames.
- B.The speed of light varies with the observer's motion.
- C.Gravitational fields affect the speed of light.
- D.Time passes faster in moving frames.
Model answer
What a good answer should say
- The laws of physics are the same in all inertial frames.
Explanation
Why this works
formula/rule: Principle of relativity – the laws of physics are invariant in all inertial frames; substitution: none; working: none; answer: The laws of physics are the same in all inertial frames.; units/conclusion: This statement captures the principle of relativity for inertial frames.
