In that case you might want to check:



And if you are thinking about making a 3D game you might want to consider using Castle Game Engine instead of FMX.
Castle Game Engine is written in Object Pascal and uses the above mentioned Kraft Physics Engine. By using CGE you will also get much better graphical performance since its renderer is much more optimized than the one from FMX. Not to mention that it offers a lot of other game related features that you would have to implement by yourself for FMX.
