Try and work out thegravitational forcebetween two objects in terms of a quantum graviton, however, and you quickly run into trouble—the answer to every calculation is infinity. Weight is thegravitational forceof attraction exerted on a body. ...

:weight 3 a :the gravitational attraction of the mass of a heavenly body (as the earth) for bodies at or near its surface b :a force of attraction between particles or bodies that occurs because of their mass, is stronger as mass is increased, and is weaker as the distance between the...
Weight, the normal force and Newton's third law: Dislodging a deeply embedded misconception Perhaps paradoxically, they help prove that the gravitational force exists, and they offer clues as to why it has such pull. The gravitational force of federal law Those columns are the gravitational force...
We have a sort of fourth-dimensional lens that concentrates the lines of any gravitational force. FromProject Gutenberg Moreover, the fact of atmospheric pressure is itself a case of one of the commonest of all facts—weight or gravitational force. ...

Suddenly we realize that weight and mass are not the same thing! Away from the earth the force of gravitation changes. As the pull gravitation changes weight changes but the mass of an object stays the same anywhere in the universe— whether it is on earth on the moon or on Mars. Have...
