Vector Product (Cross Product): The vector product, also known as cross product, is another mathematical operation involving vectors. Unlike scalar product which results in a scalar quantity, vector product produces another vector perpendicular to both input vectors.

Magnitude of Vector: The magnitude of a vector refers to its size or length. It is a scalar quantity that represents the distance or strength of the vector.

Unit Vector: A unit vector is a vector with a magnitude of 1. It is often used to represent direction and can be multiplied by a scalar to indicate magnitude and direction simultaneously.
