Page 150 - Archimedes stated that a body immersed in a fluid is buoyed up by a force equal to the weight of the displaced fluid.
Page 40 - Newton generalized the law of attraction into a statement that every particle of matter in the universe attracts every other particle with a force which varies directly as the product of their masses and inversely as the square of the distance between them; and he thence deduced the law of attraction for spherical shells of constant density.
Page 219 - The heat which is expended in changing a body from the solid to the liquid state, or from the liquid to the gaseous state, is called latent heat.
Page 13 - It is evident that a body can not exist without possessing the three attributes of length, breadth, and thickness. The FORM of a body is its external shape. Bodies may have the same magnitude and be very different in shape ; they may likewise be of the. same form and yet be of very different magnitudes. Impenetrability. 7. IMPENETRABILITY is that property by virtue of which no two bodies can occupy the same place at the same time.
Page 14 - INERTIA is the tendency which a body has to maintain its state of rest or motion. If a body is at rest it has no power to set itself in motion, or if it is in motion it has no power to change either its rate of motion or the direction in which it is moving. Hence, if a body is at rest, it will remain at rest, or if in motion, it will move on uniformly in a straight line until acted upon by some force. The reason why we do not see bodies continue to move on uniformly in straight lines, when set in...
Page 188 - By repeating this operation a few times, the bulb and a portion of the tube are filled with mercury. The whole is then heated till the mercury boils, thus filling the tube, when the funnel is melted off and the tube hermetically sealed by means of a jet of flame urged by a blow-pipe. On cooling, the mercury descends to some point of the tube, as shown in O.ffe.
Page 275 - The following definitions apply equally to concave and convex mirrors : The middle point of the mirror is called its vertex. The centre of the sphere, of which the mirror forms a part, is called the optical centre.
Page 149 - But a caution as to the necessity in all specific gravity experiments of getting rid of air-bubbles may not be out of place. To attain this end boiled water should be used, and if mechanical contrivances fail (a feather or sable pencil) then the liquid and stone should be placed under the receiver of an airpump and the air exhausted. Details concerning the specific gravity of each kind of precious stone will be found in chapter vi.
Page 43 - The weight of a body is due to the force of gravity, acting upon all of its particles, but it must not be confounded with the force of gravity. Weight is only the effect of gravity when resisted ; when gravity is unresisted it produces quite another effect, that is, motion. At the same place the weights of bodies are proportional to their masses, or the quantities of...
