 1 I  |   applied has been expended and lost, leads us to a further characteristic
 2 I  |   exhausted. Its gravity is not lost or diminished; it is attracted
 3 I  |      motion of the clockwork is lost. It can only keep the weight
 4 I  |      reached the bottom, it has lost none of its gravity, it
 5 II |        bullet, that velocity is lost, as such, when it produces
 6 II |         their velocity has been lost by the work which they have
 7 II | imparted to the pendulum is not lost in these oscillations provided
 8 II |    Something, however, has been lost - the gunpowder, that is
 9 II |    formerly seemed to have been lost. Heat was said to have become
10 II |        started it, is gradually lost in consequence of friction.
11 III|         therefore, motion seems lost in friction and impact,
12 III|      impact, it is not actually lost, but only passes from the
13 III|        its capacity for work is lost. Hence the two elements
14 III|     capable of work, it is here lost. The electrical current
15 III|     restore work which has been lost, but only by using another
16 III|  quantity of mechanical work is lost, there is obtained, as experiments
17 III|        conversely, when heat is lost, we gain an equivalent quantity
