Now if i know the position vector of my periapsis, and the absolute value of my velocity at that position. How do i calculate my velocitys direction. I mean is it just the tangential unit vector in shperical coordinates?
If the radius of curvature is perpendicular to the tangential velocity how is there not a tangential component to the gravitational force. I basically don't understand the top point you have drawn. If there is a tangential component to the gravitational force how is there no torque applied at your upper point?
Was searching for this since an hourr and finally got it
Thank you so much for such a clear explanation
@ 1:19 Great proof :-(

Great!
