The resulting answer can be found by multiplying the scalar projection of vector \vec{u} onto vector \vec{v} by a unit vector in the direction of \vec{u}.

The resulting answer can be found by multiplying the scalar projection of vector \vec{u} onto vector \vec{v} by a unit vector in the direction of \vec{v}.

The resulting answer will be the perpendicular component of \vec{u} in the direction of  \vec{v}.

The resulting answer will be the perpendicular component of \vec{v} in the direction of  \vec{u}.

The resulting answer will be a scalar quantity.
