 Current Topic:Rotation as a vector The problem with James' question is that it is imprecise ! Yes, linear displacement is a vector; where both angle & magnitude must be incorporated into mathematical operations, arithmetical, algebraic and differential . "Rotatation" however is imprecise. Is this to mean angular displacement, velocity, or acceleration ? If angular displacement, then NO !, angular displacement is NOT a vector. If angular velocity, then YES !, angular velocity is a vector. If angular acceleration, then YES !, angular acceleration is a vector. The previous post, from "Dr Funda", suffers from imprecision of the kind identified here. ozogg, Eng'g Lecturer (ret. after 35years).
