Best Answer

The force of gravity between the Earth and you or any other object is inversely

proportional to the square of the distance between the centers of the Earth and

the object.

On the surface, that distance is the Earth's radius, let's say 3,960 miles on the average.

(3,960/4,080)2 = 0.942

So your weight at an altitude of 120 miles is about 5.8% less than it is on the surface.

Tocalculate the area of the front surfaceof a box?

The front surface of a box is a rectangle. If you only need the area of the front surface, then it doesn't even matter what it's part of. Multiply the width of the surface by its height. The answer is its area.

Is there a planet with more gravity than earth?

This question is probably about the strength of the "surface gravity" of the planets. "Jupiter" is the obvious answer. It has a surface gravity about 2.5 times Earth's. Neptune also has a higher surface gravity than Earth. (Sometimes Saturn is given as another example, but it depends on the exact definition of "surface gravity".)


How does the Moon's gravity compare to the sun's?

At their respective surfaces, the acceleration of gravity, and therefore theweight of each unit mass, is 2.28 times as great on Mercury compared toits value on the moon. The moon's is 43.9% as great compared to Mercury's.Mercury . . . 3.697 m/s2 . . . 37.7% compared to EarthMoon . . . 1.623 m/s2 . . . 16.55% compared to Earth
