光速为什么用符号c表示,c代表什么吗? 请指点!谢谢!

借用一下二楼的,谢谢了

c可能代表拉丁词语celeritas,这个词的意思是快速的.Celerity(迅速,敏捷)也是英语中很少用来形容速度的词,英语中accelerate(加速)和 decelerate(减速)都用到了这个词根.

就是个符号,没别的意思,爱因斯坦用的它,人们就延续着用

Why is c the symbol for the speed of light?
The symbol c seems to have been used for the speed of light (in vacuum) for a long time. Einstein used other symbols such as V in his early relativity papers but most early books on relativity used c.
It probably stands for the Latin word celeritas meaning swift. Celerity is also an infrequently used word in English for speed and the same root is usedin the words accelerate and decelerate.
It would be interesting to know more about who used c for the speed of light(or other speeds) before the twentieth century.

C 代表 光速
