The earth's rotation (A) increases, (B) decreases, or (C) does not affect its gravitational binding energy.
A) increases
B) decreases
C) does not affect its gravitational binding energy

Question

Quizplus · Accepted Answer

The earth's rotation decreases its gravitational binding energy because as the Earth rotates, it bulges at the equator due to centrifugal force, which slightly reduces the overall gravitational pull between its particles, thus decreasing its gravitational binding energy.
