  It helps understanding the gravity slingshot if you think of the effect
as a 100% elastic collision. If you do the math, you will see how the
larger object transfers momentum to the smaller object in such a collision.
And elastic collision is, AFAIK, exactly what the effects of a gravity
assist are, from an overall point of view.
