| Jun 16, 2023 at 11:54 | comment | added | Dale | @VincentFraticelli yes, a spring with a mass is an accelerometer. You make a good point. I prefer the standard relativistic definition, and that definition is compatible with classical mechanics (Newton Cartan gravity). But it is true that some Newtonian books do identify a free falling frame as non-inertial. I have added a paragraph to that effect. I think it is a bad approach, but it is often found in introductory textbooks (others just avoid the issue altogether, which I prefer). So the OP should be aware | |

| Jun 16, 2023 at 5:43 | comment | added | Vincent Fraticelli | @Dale Could you give an exemple of such an accelerometer ? If I take a spring with a mass, would it be OK ? If yes, I would find that a free falling frame at earth surface is an inertial frame. And in the classical point of view (not the relativistic one), such frame is not usually considered as "inertial" ? | |

| Jun 15, 2023 at 10:20 | comment | added | Priyanshu Chauhan | ok! but i did not get it. you are saying that inertial frame is at rest with respect to itself,but all frame are at rest with respect to itself. and another thing, that is you are saying that the acceleration of frame is measured with respect to acceleometers,but i am not able to get a accelerometer during my exam and to whom respect these accelerometers measured acceleration of frame | |
| Jun 15, 2023 at 0:38 | comment | added | Dale | @PriyanshuChauhan I don’t like a big barrage of follow up questions. An inertial frame is at rest with respect to itself. It is moving uniformly with respect to other inertial frames. You cannot know if a frame is inertial from numericals, it is something determined experimentally as I described. The property of not accelerating is intrinsic to the frame and is not something determined with respect to any other frame, it is measured within the frame itself using accelerometers. Please do not ask another barrage of follow up questions. If you have other questions then post them as new questions | |
| Jun 14, 2023 at 22:08 | comment | added | Priyanshu Chauhan | "In classical physics and special relativity, an inertial frame of reference (also called inertial reference frame, inertial frame, inertial space, or Galilean reference frame) is a frame of reference that is not undergoing any acceleration. " this is what written on WIKIPEDIA i just to want to know that to whom respect that the inertial frame is not undergoing any acceleration? | |
| Jun 14, 2023 at 22:02 | comment | added | Priyanshu Chauhan | during solving physics numericals how would i know that the frame is inertial or non inertial ? | |
| Jun 14, 2023 at 21:59 | comment | added | Priyanshu Chauhan | I just want to know only that the inertial frame is at rest or moving with constant velocity to whom? is it any other frame of reference or universe ? | |
