...acting oa the fingle Particle A ; fince then each fingle Particle AGAIN : Since the Attraction is always directly as the Quantity of Matter, and inversely as the Square of the Diftance, it follows, that were the internal Parts of the Earth a perfedt Void, or hollow Concavity,...

...and on the distance of the body which is acted upon. The force of gravity, therefore, is said to be directly as the quantity of matter, and inversely as the square of the distance. As these expressions occur frequently in the course of this work, it will be useful to the...

...Newton's Principia, and inform us, that this great and immortal philosopher proved that attraction is directly, as the quantity of matter, and inversely as the square of the distance—Then by the help of a diagram and some algebraic formulae of his own invention, he might...

...distance of the body upon which that force is exerted. The force of gravity, therefore, is said to be directly as the quantity of matter, and inversely as the square of the distance. As these expression! occur frequently in the course of this work, it will be useful to the...

...tends toward the central body, C, is called a centripetal force ; and in the case of gravitation, it is directly as the quantity of matter, and inversely as the square of the distance. The force by which the revolving body, B, tends to move along the line, i,/,is called a centrifugal...

...Thus we speak of the law of gravitation, of reflection, of acceleration, and say, that attraction is directly as the quantity of matter, and inversely as the square of the distance, — that rays of light are reflected, making the angle of incidence equal to the angle of...

...constitution of things ; and is as truly a law of the physical universe, as that its gravitation is directly as the quantity of matter, and inversely as the square of. the distance. then the numerical relations would not be in the least disturbed, only the numbers expressing...

...cause of their weight, or tendency to approach the centre of the earth. The force of gravitation is directly as the quantity of matter, and inversely as the square of the distance. The quantity of matter being given, and the attracting force at a certain distance, say four...

...by Sir Isaac Newton, as the necessary result of a still more general law, viz. that gravitation is directly as the quantity of matter, and inversely as the square of the distance. Thus, if the distance of but one planet from the sun be known, and the periodic revolutions...
