How far off the ground can objects begin to "lose" weight? And if you're atop the Everest, will your weight have changed?

Your weight will have changed very slightly seeing as how it takes 20 moons distance to escape the gravity of the Earth or feel weightless.

The amount of force (or weight) exerted by a massive body is governed by the equation weight = (GMm)/ (r^2) where G is a constant and M is the mass of the Earth , m is your mass, and r is the distance from the center of the planet. Since G, M, and m stay the same the weight = Constant / (r^2). If you weigh 200 lb at the surface of the Earth this is 1 Earch radius so 200 = constant / (1^2) and constant = 200. Using this equation, here are weights at different multiples of Earth's radius
Earth
Radius Weight (lb)
1= 200 lb
2 = 50 lb
3 = 22 lb
4= 13 lb
5 = 8 lb

About 200 miles... depending on the speed you're traveling. You would be lighter on Everest, but the ammount is very insignificant.
