刚刚看课本
里面写到
Scientists spoke of the mass increasing at high speeds. We prefer to keep th
e concept of mass as an invariant, intrinsic property of an object. The use
of the two terms relativistic and rest mass is now considered old-fashioned,
although the terms are still some times used. We always efer to the mass m,
which is the same as the rest mass. The use of relativistic mass often lead
s to mistakes when using classical expressions.
相对论和静止的质量这个概念已经过时了
我们在使用m时就是指静止质量
靠北，所以到底要不要用相对论质量阿

用

我以前看书都说速度接近光速时质量会变成无限大，这也是骗我的吗==

拉马努金都自己想
