| Aug 28, 2018 at 13:56 | comment | added | Mathphys meister | The only thing you can do is show that the Lagrangian gives the desired force that you claimed, then the Lagrangian describes the system. This is a derivation done in e.g. Goldstein. | |
| Aug 28, 2018 at 13:55 | comment | added | Mathphys meister | I am sorry I thought that i found a way of deriving it but I do not know how to show it without this guess! For the moment just to try to accept it, I hope somebody can help you out! | |

| Aug 26, 2018 at 14:02 | comment | added | Mathphys meister | I am afraid that the only answer I can give is that it is indeed an educated guess... It just seems to be consistent with the previous results | |
| Jul 30, 2018 at 14:02 | comment | added | Tamir Vered | @cobra121 I'm aware of that but it bugs me to think that this Lagrangian is just an "educated guess" that just in case gives us the correct force... That's why I want to see a derivation. | |
