11. Under this condition, conservation of mass implies that the vertical velocity of the fluid is small. 12. 2002 saw a notable modification to Vertical Velocity . 13. Vertical velocity at the surface is 13.6 m s " 1, indicating strong rising motion.14. A third instrument, the vertical velocity indicator, is likely to reveal little beyond what is already known. 15. The booster stage successfully approached the water surface with no spin and at zero vertical velocity , as designed. 16. Vertical velocities are essential for the activation of ice nuclei, but remain uncertain due to lack of observations.17. The bullet along with its decelerating vertical velocity has an initial horizontal velocity of 4.63 m / s. 18. Result : the ball has lots of vertical velocity and stays up in the air for a long time. 19. The aircraft continued to rotate through a further 360 degrees on momentum alone, having lost nearly all vertical velocity . 20. Since the vertical velocity is zero at the impermeable horizontal bed " " h " } }.
