The cross product (A × B) is a vector whose magnitude is given by:

| A × B | = |A||B| sinθ

Its direction follows the right-hand rule.

Explanation

Work, mass and distance are scalar quantities because they have magnitude but no direction, but they are not vector quantities.

Vector Quantities: Velocity, momentum, torque, acceleration, weight, displacement.

Scalar Quantities: Work, distance, speed, mass.

Explanation

The cross product of two vectors A × B ≠ B × A; in fact, A × B = –(B × A), so it is not commutative.

However, it does obey the distributive law over addition, and associative law applies with scalar multiplication but not for three vector cross products.
