Recently I came across the following thought experiment :
Take a string and whirl it in a horizontal circle. Imagine that an ant is sitting on the string . From our point of view , the ant is in accelerated motion. But from the point of view of the ant , it is us who’s in accelerated motion.
Now this probably follows from the fact that rest and motion are only relative terms. We can only be at rest or in motion relative to a frame of reference. However , this holds only when the motion is non accelerated. I believe that since the ant can feel that it’s undergoing acceleration this does not hold true right ? Please advise me about your opinion. Thank you !
