The gravitational force on an object on the surface of the Moon is 16 that of the gravitational force on the same object on the surface of Earth. Why is the gravity acting on the object on the Moon less than the gravity acting on the object on Earth?

• • because the distance from Earth to the object has increased

• • because the mass of the Moon is less than the mass of Earth

• • because Earth is rotating at a faster rate than the Moon is rotating

• • because the pull on the object from Earth
