When I think of the gravitational pull of a large body of mass with a magnet, I see a similarity...attraction.
The longer the distance between two magnets, the weaker the attraction. Does gravity behave in a similar manner? For example, when I'm flying 30,000 feet in the air, do I weight less? In the ISS, gravity is measured as "micro-gravity".
Is there a breaking point between 30,000 feet and the ISS where there is a sudden change in attraction to the earth or is it gradual?
I'm just wondering because you hear about weightlessness in space all the time but I have never heard of weighing half as what you weight at sea level at a certain hight.
