41. The jettison during daylight allowed the astronauts and flight controllers to accurately track its position and relative velocity . 42. A headwind will slightly increase the relative velocity of the projectile, and increase drag and the corresponding drop. 43. In the present context, all velocities are best thought of as relative velocities of frames unless otherwise specified. 44. The effect of expansion of steam over the moving blades is to increase the relative velocity at the exit. 45. Turbulence in the protoplanetary disk disk can create density fluctuations which exert torques on planetesimals exciting their relative velocities . 46. The slope of the world line ( deviation from being vertical ) gives the relative velocity to the observer. 47. This means of course that the relative velocity vectors have to be directed radially outward with respect to the observers. 48. If Aldebaran had zero relative velocity , it would require more than two million years for the spacecraft to reach it. 49. Of course, the mechanism works the same for all masses of interacting bodies and for any relative velocities between them. 50. Then the magnitude of the relative velocity of any point in the circumference of the disk is \ omega R.
