    Vector Product of Parallel Vectors

    When two vectors are parallel or antiparallel, their vector product is zero.

    Vector Product of a Vector with Itself

    The vector product of any vector with itself is always zero.

    Scalar Quantities

    Scalar quantities are physical quantities that can be described by a single numerical value and a unit.

    Vector Quantities

    Vector quantities are physical quantities that require both a magnitude and a direction to be completely described.
