What is the gravity of moon as compared to the Earth
1/4 th of Earth
1/5 th of Earth
1/6 th of Earth
1/8 th of Earth
1/6 th of Earth
The Moon’s surface gravity is about 1/6th as powerful or about 1.6 meters 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.
