Thus, the law of the motion of a planet is resolved into the law of the tangential force, which tends to produce an uniform motion in the tangent, and the law of the centripetal force, which tends to produce an accelerating motion towards the sun; the real motion being a compound of the two.

The tendency of the moon towards the earth being ascertained to vary as the inverse square of the distance, it was deduced from this, by direct calculation, that if the moon were as near to the earth as terrestrial objects are, and the tangential force were suspended, the moon would fall towards the earth through exactly as many feet in a second as those objects do by virtue of their weight.

They were almost oppressively brilliant, seen through the clear, cold atmosphere, and as The Hopper slipped from one big tree to another on his tangential course to the house, he fortified his courage by muttering, "They's things wot is an' things wot ain't!"
