I have read quite a few forum posts and wiki entries on the oberth effect and would like to ask you guys if my observation are correct: Reasons for the Oberth Effect: 1) Work = Force (your Engine) times distance (distance covered while thrusting) 2) When firing at periapsis, you loose mass that you then don't have to carry up to apoapsis again, so the remaining ship can go higher Questions: 1)Does this also apply to slowing down? 2)Will your spacecraft accelerate faster if the planet you are orbiting is at periaps, too? Thanks, looking forward to your answers!
