Could you explain how a sattelite can pick up more speed after circling the sun? I believe it is called the slingshot effect? Wouldn't any speed gained from the gravitational pull of the sun be counteracted by the same gravity when the sattelite was distancing itself from the sun?
for a clear answer using basic principles of momentum
and energy conservation.
