My astronomy book tried saying that the moon is spinning into outer space, away from earth,; it was blamed on tidal effects between the earth and moon and the subsequent generation of frictional forces. I dont see it. Also, from physics, if you look at a force diagram there should only be weight acting on the moon pulling it towards the earth, so there would be a net force towards earth. but the moon is drifting into space (confirmed by nasa experiments), so how is this possible. my physics teacher couldnt understand what i was saying.
