PPhysicist248 replied to the thread Undergrad Linear vs rotary motion.Yeah, that was basically my question: relative to what observer?
-
PPhysicist248 replied to the thread Undergrad Linear vs rotary motion.And how do you think inertial navigation systems work?
-
PPhysicist248 replied to the thread Undergrad Linear vs rotary motion."GR is non-Machian" Hmm. In layman's terms, does the mass in the large universe cause the local centrifugal force (according to GE)?

PPhysicist248 replied to the thread Undergrad Linear vs rotary motion.Let's say I choose the earth as the frame of reference. I.e. the earth is motionless with respect to that frame. Why is it experiencing...

PPhysicist248 replied to the thread High School Car spinning on a frictionless sheet of ice = absolute motion?.If the universe is rotating around the car why is the car experiencing centrifugal forces?

PIf linear motion is relative, how come that rotary motion is absolute? And if it is not absolute what is is relative to?
