Change in Velocity (Delta-v)
Space missions hinge on mastering the delicate balance of velocity changes and fuel limits

Why is delta-v considered a scalar measure of impulse rather than a direct physical change in velocity in spacecraft dynamics?
Because it represents the total impulse per unit mass required for maneuvers, not just the vector difference in velocity.
Because it only measures the speed increase of the spacecraft during launch.
Because delta-v and physical velocity change are exactly the same in all contexts.
