When dealing with vectors ("directional growth"), there's a few operations we can do: Add vectors: Accumulate the growth contained in several vectors. Multiply by a constant: Make an existing vector stronger (in the same direction). Dot product: Apply the directional growth of one vector to another. The result is how much stronger we've made ...

Definition and intuition We write the dot product with a little dot ⋅ between the two vectors (pronounced "a dot b"): a → ⋅ b → = ‖ a → ‖ ‖ b → ‖ cos ( θ)

In general, the dot product is really about metrics, i.e., how to measure angles and lengths of vectors. Two short sections on angles and length follow, and then comes the major section in this chapter, which defines and motivates the dot product, and also includes, for example, rules and properties of the dot product in Section 3.2.3.

$\begingroup$ The convention, that the cross product of two vectors is represented by the right hand rule, is consistent with the convention of our coordinate system, the cartesian coordinate system. But I want supplement Steeven. In nature there are phenomena that really can be described with vector cross product.

Be careful not to confuse the two. So, let’s start with the two vectors →a = a1, a2, a3 and →b = b1, b2, b3 then the cross product is given by the formula, →a × →b = a2b3 − a3b2, a3b1 − a1b3, a1b2 − a2b1 .

The cross product could point in the completely opposite direction and still be at right angles to the two other vectors, so we have the: "Right Hand Rule" With your right-hand, point your index finger along vector a , and point your middle finger along vector b : the cross product goes in the direction of your thumb. The cross product gives the way two vectors differ in their direction. Use the following steps to use the right-hand rule: First, hold up your right hand and make sure it's not your left, Point your index finger in the direction of the first vector, let a →. Point your middle finger in the direction of the second vector, let b →.The direction of the vector product can be visualized with the right-hand rule. If you curl the fingers of your right hand so that they follow a rotation from vector A to vector B, then the thumb will point in the direction of the vector product. The vector product of A and B is always perpendicular to both A and B.Dot product. In mathematics, the dot product or scalar product [note 1] is an algebraic operation that takes two equal-length sequences of numbers (usually coordinate vectors ), and returns a single number.

Geometrically, the scalar triple product. is the (signed) volume of the parallelepiped defined by the three vectors given. Here, the parentheses may be omitted without causing ambiguity, since the dot product cannot be evaluated first. If it were, it would leave the cross product of a scalar and a vector, which is not defined. This is called a moment of force or torque. The cross product between 2 vectors, in this case radial vector cross with force vector, results in a third vector that is perpendicular to both the radial and the force vectors. Depending on which hand rule you use, the resulting torque could be into or out of the page.
