== Mass depending on direction ==
The article states:
:''There is a logical difficulty, however, to an increase in relativistic mass. Such increase would only exist in the direction of motion, and the rest mass would remain intact with respect to a force applied in a direction orthogonal to velocity. Neither mass nor energy is a vector, and the notion of the mass of an object having different values depending on the direction of an applied force is illogical.''
As [[User:RSchlafly|RSchlafly]] on 8 July 2007 (EDT): ''This paragraph is nonsense [..] The relativistic mass applies no matter what the direction of the force is.''
