"Physics also applies to her."

Translation: Physik gilt auch für sie.

[Matthias1414]

"Physik betrifft auch sie" could be another possibility.

[thutson]

Anything wrong with: "Physik gilt ihr auch." ?

[Jrgen792736]

Das klingt etwas komisch, da ja die Physik Naturgesetze und keine Anweisungen enthält.

[Timxj220]

Warum ist es Für nicht zu?
Irgendwas mit die fälle machen?

[quis_lib_duo]

The verb gelten uses für to designate to whom it applies.

[Ly_Mar]

Also, I think it should be ‘irgendwas mit den Fällen/Kasus zu tun?’ (assuming you meant to say ‘something to do with the cases?’), but I don't know whether you can use the expression this way.

[Patrick187019]

I have a problem understanding the meaning of gelten. If it means 'to be valid' what is the sentence saying? Does anyone have a better example for the verb?

[Ly_Mar]

Yes, it means “to be valid, to hold true, to count” or “to be of value”. The first meaning is being used here: “physics holds true for her too”. Another example could be “diese Regel gilt immer noch” (“this rule is still valid/still in force”) or “das gilt als vollständig” (“that counts as/is deemed complete”).

[CalmlyBallistic]

I'm confused on when it's just a noun "Physik" and article+noun "der Physik". German seems to use articles more often, but unpredictably so.

[MuhammadSRashed]

Would "gilt sie auch für" be fine?
