Is the force of attraction between two objects?
Gravitational force -an attractive force that exists between all objects with mass; an object with mass attracts another object with mass; the magnitude of the force is directly proportional to the masses of the two objects and inversely proportional to the square of the distance between the two objects.
Why is the force of gravity weaker on the Moon than on Earth?
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.
Why doesn’t the Moon have an atmosphere?
Our Moon doesn’t have an atmosphere because it is too small and doesn’t have a strong magnetic field. Any atmosphere it might have had would be stripped away by the solar wind that barrages the small world. In contrast, our planet has more mass to hold its atmosphere close, and a strong magnetic field to protect it.
