A) Planet A has more kinetic energy, less potential energy, and less mechanical energy (potential plus kinetic) than planet B.
B) Planet A has more kinetic energy, more potential energy, and more mechanical energy (potential plus kinetic) than planet B.
C) Planet A has more kinetic energy, less potential energy, and more mechanical energy (potential plus kinetic) than planet B.
D) Planet A and planet B have the same amount of mechanical energy (potential plus kinetic) .
