Hi Doc Al, lpfr, thanks for your explanations, now I fully understand :smile: And yes lpfr, I see why the distance is greater, it is because it moves along a circular path !

I know that when I apply a Force on the center of gravity of a body, I generate a linear motion and no rotation around any axe. (supposing here there is no drag) Now when I apply the same force off COG, I get a torque T = F.d making the body rotate AND a linear velocity, which is strictly...

(to the moderators : forgive me if I posted in the wrong topic, but maybe there should be an 'numerical analysis' topic in the programming sub-forum, and dedicated to physics simulation programming ?) Hi D H, Thanks this is exactly the kind of suggestions I sought for :) I agree with most of...

Hi Sane, chroot, actually I don' t want to focus on the 3D and graphical stuff, my concern is about developing first an orbital physics library, which would support one ore more spacecraft orbiting Earth and being able to exert thrust forces, so my concern is about choosing an integrator...

Hello, I plan to write a (modest) orbital simulator in C++, I am an experienced developer with an average knowledge of classic physics; I would like to have some recommendations (recommended book reading, eventual existing C++ libraries that can help) before starting knowing that I need...
