Question

velocity n.速度；迅速；速率 (1) 那辆汽车的速度简直太快了！(2) 声音在水中的速度是在空气中的速度的4倍多。(3) 羚羊跑起来速度惊人。(4) 光速大约是每秒十八万六千英里。 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."

If your rocket is traveling at maximum velocity, it means it can't go any faster. Velocity is quickness of motion or action. 1[N-VAR 可变名词]速度；速率 Velocity is the speed at which something moves in a particular direction.   [TECHNICAL 术语]...the velocity of light.光速...the velocities at which the stars orbit.恒星沿轨道运行的速度...high velocity rifles.高速步枪
