Answer:
1) The gravity on the moon is 1.62 m/s² which means the moon rotates with force using gravity.
2) 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.
3) The moon pulls on the Earth with the exact same magnitude of force that the Earth pulls on the moon since it is the same interaction. But wouldn't this also make the Earth move in a circle? Yup. Essentially, it does.
4) The mass of one object is doubled
If the mass of one of the objects is doubled, then the force of gravity between them is doubled. ... Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces.
