How the physics engine works on android and iOS?

I was just wondering how the physics engine works on android and iOS. Is the physics exec code from PhysX included in the APK, or somewhere else? I know that PhysX is built into Nv cards, and runs as a runtime on other GRU’s. Thanks

That code is an integral part of the Unity binaries, which sits inside the .apk.

It’s doesn’t in Unity, it’s just CPU only.
