-- A spacecraft is flying from Earth toward the moon. -- The gravitational forces between the Earth and the spacecraft are steadily decreasing. -- The gravitational forces between the Moon and the spacecraft are steadily increasing. I did a calculation to see where the spacecraft would need to be in order for the gravitational force pulling the spacecraft toward the Earth and toward the Moon to be equal.  I came out with just about 90% of the distance to the Moon.  That happens because gravitational force depends on mass, and the Earth has about 80 times as much mass as the Moon has.
