Its relativistic mass would be twelve thousand two hundred tons.
Or maybe result in a higher relativistic mass that could explain a portion of dark matter/energy?
The ratio of the momentum to the velocity is the relativistic mass, m.
When the velocity is small, the relativistic mass and the rest mass are almost exactly the same.
Some claim that (in later years) he did not like the idea of "relativistic mass."
In this case, its total relativistic mass and energy increase.
Only if you're using relativistic mass, which can only be used in special relativity.
That is sometimes called the "relativistic mass" of the object.
In the following, N is given in terms of the rest and relativistic masses.
Since turnover, the ship had shed most of its enormous relativistic mass.
