"Center of gravity" Quotes from Famous Books
... South. The Latin-American States which, to their disadvantage, have been off the main lines will now be on the main lines. I feel that these gentlemen honoring us with their presence to-day will presently find that some part, at any rate, of the center of gravity of the world has shifted. Do you realize that New York, for example, will be nearer the western coast of South America than she is now to the eastern coast of South America? Do you realize that a line drawn northward parallel with the greater part of the ... — President Wilson's Addresses • Woodrow Wilson
... then devised a graded scientific set of exercises. The system is really not a lot of tricks, but is based on the elementary laws of mechanics, a study of the equilibrium of the human body, the ways in which it is disturbed, how to recover your own and take advantage of the shiftings of the center of gravity of the other person. The first thing that is taught is how to fall down without being hurt, that alone is worth the price of admission and ought to be taught in all our gyms. It isn't a good substitute for out-of-door games, but I think ... — Letters from China and Japan • John Dewey
... points in a direction almost normal to the surface of your planet. These devices tap and use the enormous force of gravity itself and when they are locked to your planet, they are anchored to the center of gravity of the planet. Unless it were normal to the planet's surface, its reactive force is so great that it would disrupt the balance which holds the planet in place were the beam sent off on ... — Giants on the Earth • Sterner St. Paul Meek
... at rest and we can not say (as anything absolute) which of the balls has lost and which has gained energy. If there is such a thing as absolute energy of motion it is something entirely unknowable to us. Take the solar system, supposed isolated. We may take as our origin of coordinates the center of gravity of the system. Or we may take an origin with respect to which the center of gravity of the solar system has any (constant) velocity. The kinetic energy of the earth, for example, may have any value whatever, and the principle ... — A Librarian's Open Shelf • Arthur E. Bostwick
... he caused two empty shell boxes to be attached to his waist, an improvised life-preserver, and thus prepared leaped overboard. In the hurried adjustment of the shell boxes, sufficient care was not taken to maintain the center of gravity, the unfortunate gentleman failed to keep his head above water, and before aid could be derived from his struggling ... — The Story of the Kearsarge and Alabama • A.
