• ### Cross Product (vector Product) - Definition,

2018-5-2 · (The cross product of two vectors is a vector, so each of these products results in the zero vector, not the scalar (0).) It’s up to you to verify the calculations on your own. Furthermore, because the cross product of two vectors is orthogonal to each of these vectors, we know that the cross product of (mathbf{hat i}) and (mathbf{hat …

2004-11-5 · The cross product (or vector product) between two vectors A and B is written as AxB. The result of a cross-product is a new vector. We need to find its magnitude and direction.

A vector is an object that has both a magnitude and a direction. Geometrically, we can picture a vector as a directed line segment, whose length is the magnitude of the vector and with an arrow indicating the direction. The direction of the vector is from its tail to its head. Two vectors are the same if they have the same magnitude and direction.
