Q
T^2 =
A
4pi^2r^3/GM
2
Q
In a circular orbit, a satellite’s speed and distance above the mass it is orbiting is constant so…
A
The kinetic and potential energy are both constant
3
Q
In an elliptical orbit, a satellite will speed up as the height decreases and slows down as the height increases…
A
The kinetic energy increases as the potential energy decreases (and vice versa) so the total energy remains constant.
