| Apr 5, 2023 at 3:39 | comment | added | user324939 | Well Newtonian mechanics can be derived from the GR in small limits, but the reality is that gravity is fictitious force, and I'll go to length quoting KK theory that even electromagnetic force can be regarded as fictitious, if one were to accept that there's a 4th dimension of space. I.e. 5 dimensional space-time | |
| Apr 5, 2023 at 3:34 | comment | added | DanDan面 | That is true if we're working in GR, but I think OP is working in the Newtonian framework, where gravity is modelled by a real, rather than fictitious force | |
| Apr 5, 2023 at 3:32 | comment | added | user324939 | Every fictitious force is same as gravity, and you can't distinguish it by any experiment from a fictitious force. That's equivalence principle . | |
| Apr 5, 2023 at 3:29 | comment | added | DanDan面 | Well, for one, it has an action-reaction pair, which fictitious forces lack | |
| Apr 5, 2023 at 3:28 | comment | added | user324939 | Does it have all the properties of a fictitious force?? Does it vanish in the inertial frame of reference? | |
| Apr 5, 2023 at 3:26 | comment | added | DanDan面 | I'm pretty sure gravity isn't a fictitious force | |
