Jennifer is inside her windowless space station laboratory and finds herself increasingly pulled to the floor. What experiment can she perform inside the lab to decide if she is feeling the effect of an acceleration or an effect of gravity?
What will be an ideal response?
None. The Equivalence Principle says no experiment performed in a closed system can distinguish between the two effects.
