Satellite Orbit: Energy and Momentum at Two Points

Moderate

For the elliptical orbit shown in the figure above, which of these statements is true about Points A and B?

A

The mechanical energy of the system and the angular momentum of the satellite around the planet are greater at Point A than at Point B.

B

The mechanical energy of the system is the same at Points A and B, but the angular momentum of the satellite around the planet is greater at Point A than at Point B.

C

The mechanical energy of the system and the angular momentum of the satellite around the planet are the same at Point A and Point B.

D

The mechanical energy of the system is the same at Points A and B, but the angular momentum of the satellite around the planet is greater at Point B than at Point A.

E

The mechanical energy of the system and the angular momentum of the satellite around the planet are greater at Point B than at Point A.
