Why does cross product give a vector which is perpendicular to a plane?

To answer your question, the cross product is perpendicular to its multiplicands because if it weren’t defined that way, it wouldn’t be too useful. Torque is a physics concept which is greatly simplified by the cross product.

What makes a vector perpendicular to another vector?

If two vectors are perpendicular, then their dot-product is equal to zero. The cross-product of two vectors is defined to be A×B = (a2_b3 – a3_b2, a3_b1 – a1_b3, a1_b2 – a2*b1). The cross product of two non-parallel vectors is a vector that is perpendicular to both of them.

What happens when you multiply two perpendicular vectors?

More generally, the magnitude of the product equals the area of a parallelogram with the vectors for sides; in particular, the magnitude of the product of two perpendicular vectors is the product of their lengths.

What happens when two vectors are multiplied?

In a dot product the operation multiples two vectors and returns a scalar product. Dot product is defined as the product of the magnitudes of the two vectors and the cosine of the angle between the two vectors. In a cross product, the multiplication of two vectors results in another vector perpendicular to them.

Why is a vector a cross product?

The cross product is mostly used to determine the vector, which is perpendicular to the plane surface spanned by two vectors, whereas the dot product is used to find the angle between two vectors or the length of the vector.

Is a vector multiplication that results to vector quantity?

One kind of multiplication is the scalar product, also known as the dot product. The other kind of multiplication is the vector product, also known as the cross product. The scalar product of vectors is a number (scalar). The vector product of vectors is a vector.

When a vector is multiplied by a scalar the product is?

The product of a scalar with vector is always a vector. Example: The product of mass ‘m’ and acceleration a gives rise to a vector quantity ‘force’.
