thanks guys, I also realized this is possible because of specific mechanical energy which is constant energy (constant) = kinetic energy + potential im really new to orbital mechanics so this went over my head

Good morning, I have a problem which I can't comprehend. I use the Trajectory Formula / Conic Section Equation of an orbit and I graphed it from 0 < Θ < 2π and with it, when I increase my velocity , my apoapsis increases as shown in the image: When I set my true anomaly to 180 degrees (apoapsis), and increase velocity... my periapsis doesn't increase in height but apoapsis continues to increase. My desired behavior is: In KSP, the periapsis angle and apoapsis angles both shifts to the correct values, but how is this done mathematically? Thanks, 5kinflute
