Is PhysX being used on mobile

When the doc mentions PhysX, does that also apply to mobile as well? PhysX is an NVIDIA technology, and many mobile phones are not using NVIDA chips, so I am wondering if that’s desktop-only.

PhysX is software-only on all platforms, and the graphics chip is irrelevant concerning physics. PhysX isn’t really nVidia technology, at least not originally; it was created by Ageia and only bought by nVidia relatively recently.
