I might have missed it, but is there (or do we know of) a different model for which the velocities actually add? Essentially, how do we go from slopes to angles

- lanternfish 5y agoIn classical Newtonian mechanics, velocities add normally a+b = c (an approximation which works near perfect for almost all velocities humans interact with). I think you might be asking a different question, though, but I'm not sure what.
- simiones 5y agoYes, he introduced it near the bottom - instead of using speeds (which are like slopes), you use "rapidities" which are the angles of the hyperbolic rotations.
