You are absolutely correct, thank you. I am trying to write this for any arbitrary launch azimuth and launch site, its just hard to remember everything that is acting on the rocket while on the ground haha.
I’m writing a 3DOF sim for a rocket. I’m having a hard time visualizing centrifugal effects from the Earth's rotation on the rocket while it is moving along the rail (acceleration > 0).
I know that once it has left the rail I no longer need to account for it since it’s in the ECI frame and...
