Σελίδα 24 - The total energy of any body or system of bodies is a quantity which can neither be increased nor diminished by any mutual action of such bodies, though it may be transformed into any one of the forms of which energy is susceptible.
Σελίδα 78 - An impressed force is an action exerted upon a body, in order to change its state, either of rest or of uniform motion in a right line.
Σελίδα 132 - ... forces describes the diagonal of a parallelogram, in the same time that it would the sides with separate.
Σελίδα 88 - Matter has an innate power of resisting external influences, so that every body, as far as it can, remains at rest or moves uniformly in a straight line.
Σελίδα 327 - ... could not differ from 71° Fahr, by more than a single degree. Now, from the Bible we learn that both plants were simultaneously cultivated in the central valleys of Palestine, in the time of Moses, and its then temperature is thus definitively determined.
Σελίδα i - And the angel of the LORD appeared unto him in a flame of fire out of the midst of a bush: and he looked, and, behold, the bush burned with fire, and the bush was not consumed.
Σελίδα 78 - This force consists in the action only and remains no longer in the body when the action is over. For a body maintains every new state it acquires, by its inertia only. Impressed forces are of different origins, as from percussion, from pressure, from centripetal force.
Σελίδα 87 - The vis insita, or innate force of matter, is a power of resisting, by which every body, as much as in it lies, continues in its present state, whether it be of rest, or of moving uniformly forwards in a right line.
Σελίδα 24 - In any system of bodies whatever, to which no energy is communicated by external bodies, and which parts with no energy to external bodies, the sum of the various potential and kinetic energies remains for ever unaltered.
Σελίδα 49 - Even water, which is a very good lubricant, is not entirely free from friction, and so our present oceanic tides must be influenced by fluid friction, although to a far less extent than the molten solid just referred to. Now all moving systems which are subject to friction gradually come to rest. A train will run a long way when the steam is turned off, but it stops at last, and a fly-wheel will continue to spin for only a limited time.
