...which are detailed in works on Physical Astronomy, that two particles of matter attract each other with a force directly proportional to the product of their masses, and inversely proportional to the square of their distance. Suppose then a particle to be attracted by all the particles of a body; if...

...Physical Astronomy, that two particles of matter placed at any sensible distance apart attract each other with a force directly proportional to the product of their masses, and inversely proportional to the square of their distance. Suppose then a particle to be attracted by all the particles of a body ;...

...to the law of Newton, which may be thus expressed : the attraction between two material particles is directly proportional to the product of their masses, and inversely proportional to the square of their distance* asunder. To illustrate this, we may take the case of two spheres which, owing...

...of action may be stated thus : — The force with which two material particles attract each other is directly proportional to the product of their masses, and inversely proportional to the square of the distances between their centres. Now the intensity of a force is measured by the momentum,...

...with a force whose direction is that of the line joining the two particles, and whose magnitude is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. This law of universal attraction is a generalization from experience,...

...resumed, " I must recall to your minds Newton's general law, ' that the attraction of two bodies is directly proportional to the product of their masses, and inversely proportional to the square of their distances.' " " Yes," said Servadac ; " we remember that." " Well, then," continued...
