Popular passages
Page 80 - Every particle of matter in the universe attracts every other particle with a force that varies directly as the product of their masses, and inversely as the square of the distance between them.
Page 49 - Change of motion is proportional to the impressed force and takes place in the direction of the straight line in which the force acts.
Page 81 - While the term gravitation is applied to the universal attraction existing between particles of matter, the more restricted term gravity is applied to the attraction that exists between the earth and bodies upon or near its surface. The law given above applies to gravity, provided that d is measured in a straight line from the center of the earth to the center of mass of the body. This line is called a vertical line, or sometimes a plumb line (from the Latin word plumbum, which means " lead "), as...
Page 186 - Jar, bent towards the negative side ; a pith ball, under similar circumstances, moves in the same direction ; when a charged Jar is placed under the receiver of an air pump, and the air is exhausted, a luminous cloud flows from the positive to the negative side, in whichever way the Jar is electrified.
Page 178 - The temperature remaining the same, the volume of a given mass of gas varies inversely as the pressure acting upon it. This may be expressed by the proportion V: V = P' : P, from which we get Pr=P'V, (42) ie PV= a constant quantity.
Page 148 - ... twenty years ago, sought to graft upon this basis a system of psychology ; and two years ago a second and greatly amplified edition of his work appeared. Those who...
Page 147 - A body immersed in a liquid is buoyed up by a force equal to the weight of the liquid displaced by it.
Page 282 - ... the specific heat of a substance is the number of calories required to change the temperature of 1 g.
Page 49 - Every body must persevere in its state of rest, or of uniform motion in a straight line, unless it be compelled to change that state by forces impressed upon it.
Page 446 - A'B = AB. This means that the image of a point in a plane mirror is on a perpendicular from the point to the mirror and as far behind the mirror as the object is in front of it.
