    Is a Comet's Momentum Conserved When Passing Near the Sun?

    Thank you for taking the time to answer... I can actually follow along with the math pretty well. And I intuitively understand how the spaceship would pick up speed... What I can't reconcile is that the total mechanical energy of the spaceship would be conserved. If it picks up twice the...
