Question

Two satellites having equal masses are in circular orbits around Earth. Satellite A has a smaller orbital radius than satellite B. Which statement is true?

A) Satellite A and satellite B have the same amount of mechanical energy (potential energy plus kinetic energy).

B) Satellite A has more kinetic energy, more potential energy, and less mechanical energy (potential energy plus kinetic energy) than satellite B.

C) Satellite A and satellite B have the same amount of kinetic energy and no potential energy because they are in motion.

D) Satellite A has more kinetic energy, less potential energy, and less mechanical energy (potential energy plus kinetic energy) than satellite B.

E) Satellite A has less kinetic energy, less potential energy, and less mechanical energy (potential energy plus kinetic energy) than satellite B.

Explanation / Answer

D) Satellite A has more kinetic energy, less potential energy, and less mechanical energy (potential energy plus kinetic energy) than satellite B
