__Product of Vectors__

The product of vectors can be either the dot product or the cross product:

**Dot Product:**The dot product of two vectors and is a scalar quantity given by , which equals , where is the angle between the vectors.**Cross Product:**The cross product of two vectors and is a vector quantity given by , which equals , where is the angle between the vectors and is a unit vector perpendicular to the plane containing and .

### Vector Products of Two Vectors

The vector products of two vectors can be categorized into the dot product and the cross product. The dot product, denoted as , results in a scalar and is calculated by , where is the angle between the vectors.

It measures the extent to which one vector projects onto another. The cross product, denoted as , results in a vector orthogonal to both original vectors and is calculated by ,

where is a unit vector perpendicular to the plane containing and . This operation is useful in physics for finding torque and rotational forces.
