Popular passages
Page 54 - Every body continues in its state of rest or of uniform motion in a straight line, except in so far as it may be compelled by impressed forces to change that state.
Page 38 - 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 60 - The total energy of any material system is a quantity which can neither be increased nor diminished by any action between the parts of the system, though it may be transformed into any of the forms of which energy is susceptible...
Page 21 - The difference between one event and another does not depend on the mere difference of the times or the places at which they occur, but only on differences in the nature, configuration, or motion of the bodies concerned.
Page 35 - Every body perseveres in its state of rest or of moving uniformly in a straight line, except in so far as it is made to change that state by external forces.
Page 87 - Rise on the earth, or earth rise on the sun, He from the east his flaming road begin ; Or she from west her silent course advance With inoffensive pace, that spinning sleeps On her soft axle, while she paces even, And bears thee soft with the smooth air along, Solicit not thy thoughts with matters hid ; Leave them to God above, him serve and fear.
Page 59 - act of producing a change of configuration in a system in opposition to a force which resists that change.
Page 114 - ... bodies is proportional to the product of their masses divided by the square of the distance between them.
Page 60 - The doctrine of the conservation of energy is the one generalized statement which is to be found consistent with fact, not in one physical science only, but in all. When once apprehended it furnishes to the physical inquirer a principle on which he may hang every known law relating to physical actions, and by which he may be put in the way to discover the relations of such actions in new branches of science.
Page 20 - All our knowledge, both of time and place, is essentially relative. When a man has acquired the habit of putting words together, without troubling himself to form the thoughts which ought to correspond to them, it is easy for him to frame an antithesis between this relative knowledge and a so-called absolute knowledge, and to point out our ignorance of the absolute position of a point as an instance of the limitation of our faculties.
