Rapidity is related to speed but isn't a speed. It is related to speed by r = arctanh(v/c) where v is the velocity.
Yes. It is the hyperbolic angle of rotation in a space-time plane due to relative velocity v (Minkowski geometry). Just like \theta is typically the angle of rotation in a space-space plane (Euclidean geometry).
