Page 159 - Principle states that a body wholly or partially immersed in a fluid is buoyed up by a force equal to the weight of the fluid displaced by it.
Page 61 - Every body continues in its state of rest, or of uniform motion in a straight line, unless it is compelled to change that state by forces impressed upon it.
Page 92 - 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 296 - ... to that required to raise the temperature of the same weight of water one degree from the temperature of maximum density 39.1 is commonly called the specific heat of the substance.
Page 161 - The specific gravity of a substance is the ratio between the weight of any volume of the substance and...
Page 199 - E ; each boy, after the transmission ot the push, becoming himself erect. E, having nobody in front, is thrown forward. Had he been standing on the edge of a precipice, he would have fallen over; had he stood in contact with a window, he would have broken the glass ; had he been close to a drum-head, he would have shaken the drum.
Page 5 - ... laboratory as it is in the ordinary recitation or lecture room. The great utility of the laboratory note-book is emphatically stated. To the objection that the kind of instruction described requires much time and effort on the part of the teacher, the Conference reply that to give good instruction in the sciences requires of the teacher more work than to give good instruction in mathematics or the languages ; and that the sooner this fact is recognized by those who have the management of schools...
Page 306 - We have now to try and realize the idea of ' a perfectly continuous, subtle, incompressible substance pervading all space and penetrating between the molecules of all ordinary matter, which are embedded in it, and connected with one another by its means.
Page 146 - The pressure per unit of area exerted anywhere upon a mass of liquid is transmitted undiminished in all directions, and acts with the same force upon all surfaces, in a direction at right angles to those surfaces.
Page 264 - The Temperature of a body is its state considered with reference to its ability to communicate heat to other bodies.
