In this case, the total virtual force exerted on both objects depends on the product of both object's energies. When one object is much more massive than the other, than you can ignore the force exerted on it, and thus ignore the mass the of the smaller object. But theoretically it still matters. | |

Mar 5, 2021 at 1:44 | comment | added | Matt | I mean, I didn't make that statement, you did. I was only confirming that it's true. | |
Mar 4, 2021 at 23:59 | comment | added | Señor O | @Matt thats a nonsensical statement. EVERYTHING has some total energy. So it has nothing to do with it having energy, it has to d with it existing. | |
Mar 4, 2021 at 21:17 | comment | added | Matt | Well gravity does affect everything that has some total energy. I never said "the same" though, obviously it depends on the amount of energy. | |
Mar 4, 2021 at 18:37 | comment | added | Señor O | I don't really get where you're seeing a legitimate issue here. I guess you're proposing we could say gravity affects everything based on its total energy, but that's flawed because that's identical to saying gravity affects everything the same because literally everything has some total energy | |
