whether a planet moves faster or slower when it is closer to the Sun.
Now I intuitively know that is [tex]\frac{dA}{dt}[/tex] is constant and the Radius r is changing. Then as r increases it moves slower and as r decreases is moves faster.
I am having trouble setting up a more formal proof.
I am thinking I will need to use the relationship [tex]L=\vec r*\vec p[/tex]
Please send a hint my way.
Thanks,
Casey
