How much is the gravity of the moon when compared with that of the earth?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) - 1/6th
The Moon's surface gravity is about 1/6th as powerful or about 1.6 meters per second per second. The Moon's surface gravity is weaker because it is far less massive than Earth. A body's surface gravity is proportional to its mass, but inversely proportional to the square of its radius.
