The discussion centers on the relativity of acceleration, drawing parallels with velocity. Participants assert that while coordinate acceleration is relative, proper acceleration is absolute and can be felt by an observer. The distinction between proper acceleration, which is independent of the observer's frame, and coordinate acceleration, which varies based on the observer's motion, is emphasized. The conversation also touches on concepts from special relativity (SR) and general relativity (GR), particularly regarding geodesic and non-geodesic motion.
PREREQUISITESStudents of physics, particularly those focusing on relativity, as well as educators and researchers interested in the nuances of motion and acceleration in different frames of reference.
Passionflower said:Well then I think the question is in same category as: "Can a chicken lay an egg while traveling on top of a photon".
That is not what is usually meant by "local", particularly in this context. Usually what is meant is that it is some experiment that you could perform in a small isolated room without reference to anything external to the room. Small means small enough in space and time to ignore any curvature.atyy said:But isn't a clock defined by a a definite integral, which is a nonlocal quantity?
