= Polar vector
{title2=$\mathbf v'=Q\mathbf v$}

A polar <vector> transforms as $\mathbf v'=Q\mathbf v$ under an <orthogonal matrix> $Q$, including an orientation-reversing transformation. Displacement, <velocity> and <force> are polar <vectors>. An <axial vector> instead transforms as $\mathbf a'=(\det Q)Q\mathbf a$.
