If your rocket is traveling at maximum velocity, it means it can't go any faster. Velocity is quickness of motion or action.

A synonym is celerity; a simpler word is speed. In physics, velocity specifically refers to the measurement of the rate and direction of change in position of an object. It is a vector quantity that specifies both the speed of a body and its direction of motion. The noun velocity descends from Middle English velocite, from Old French, from Latin vēlōcitās, from vēlōx "fast."

Definitions of velocity

n distance travelled per unit time in one direction

angular velocity
(physics) the rate of change of the angular position of a rotating body; usually expressed in radians per second or radians per minute
the speed of an aircraft relative to the air in which it is flying
escape velocity
the minimum velocity needed to escape a gravitational field
the speed of an aircraft relative to the ground
excessive velocity
muzzle velocity
the velocity of a projectile as it leaves the muzzle of a gun
peculiar velocity
velocity with respect to the local standard of rest
radial velocity
velocity along the line of sight toward or away from the observer
c, light speed, speed of light
the speed at which light travels in a vacuum; the constancy and universality of the speed of light is recognized by defining it to be exactly 299,792,458 meters per second
(nautical) the minimum rate of motion needed for a vessel to be maneuvered
terminal velocity
the constant maximum velocity reached by a body falling through the atmosphere under the attraction of gravity
Type of:
a magnitude or frequency relative to a time unit
