WebJul 18, 2024 · As you know, the dot product of two vectors is invariant under rotation, that is why it's called “the scalar product”. The cross product, also called the vector product, transforms as a vector. Now there is a final bit of the puzzle. The magnitude of a vector is also a scalar. Rotating the vector does not change its length.
