ABSTRACT
In his book, Jules Verne says that this is possible … ‘provided it possesses an initial velocity of 12000 yards per second. In proportion as we recede from the Earth the action of gravitation diminishes in the inverse ratio of the square of the distance; that is to say at three times a given distance the action is nine times less. Consequently the weight of a shot will decrease and will become reduced to zero at the instant that the attraction of the moon exactly counterpoises that of the Earth; at 45
will have no weight whatever; and if it passes that point it will fall into the moon by the sole effect of lunar attraction.’
