在日常用语中，这两个词没有区别，可以通用。而在物理学里，velocity 是一个矢量(vector quantity)表示起点与终点间直线距离的长度除以所用时间所得的量，并注明方向：而 speed 是一个数量(scalar quantity)，是指起点到终点所走过的所有路程除以所用时间所得的量，且不标明方向。
Supernatural Speed - User can move blatantly faster than other people in their universe, reaching into high superhuman territory. Type I: Users can move at a speed of 1,236-6,174 kph, moving at supersonic speeds and, in some cases, reaching hypersonic speed at their maximum speed. Type ...
speed is measured in kilometers or miles per hour . For example , a speed of 16 kilometers( 10 mi ) per hour means that something is moving fast enough to travel 16 kilometersin one hour . This speed is recorded as 16 kph( 10 mph ) . Speed can also...
China's Fuxing trains operate at a speed of 350 kph on 1,910-kilometer lines, including the Beijing-Shanghai, Beijing-Tianjin, Beijing-Zhangjiakou, and Chengdu-Chongqing routes. China is the only country in the world with commercially operated high-speed rail trains that travel at 350 kph. ...
