**called**velocity . 3. If the moving point pass over equal spaces in equal suc- cessive intervals of time , its velocity is said to be uniform . It is evident that the velocity of a moving point will be greater or less in exact proportion ... Page 5

**called**the parallelepiped of velocities . 10. From this it is clear that we may consider any given velocity to result from the coexistence of other velocities in two or three given directions , according as we deal with space of two or ... Page 6

**called**the resolved parts of the velocity v . 11. Conversely , having given the velocities in given direc- tions in space , we can find an analytical expression for the resulting velocity in magnitude and direction . This is**called**...### Other editions - View all
