# What does the dot product do to vectors?

## What does the dot product do to vectors?

The dot product essentially tells us how much of the force vector is applied in the direction of the motion vector. The dot product can also help us measure the angle formed by a pair of vectors and the position of a vector relative to the coordinate axes.

What is the rule for vector product?

Right Hand Rule, Vector Product 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.

### How do you get the dot product?

About Dot Products bn> we can find the dot product by multiplying the corresponding values in each vector and adding them together, or (a1 * b1) + (a2 * b2) + (a3 * b3) …. + (an * bn). We can calculate the dot product for any number of vectors, however all vectors must contain an equal number of terms.

Which of the following is obeyed by dot product?

Answer: Dot product of two vectors obeys commutative law.

#### What is properties of dot product?

Dot Product Properties of Vector: Property 1: Dot product of two vectors is commutative i.e. a.b = b.a = ab cos θ. Property 2: If a.b = 0 then it can be clearly seen that either b or a is zero or cos θ = 0. ⇒ θ = π 2.

Why dot product is scalar or vector?

Vector dot product is also called a scalar product because the product of vectors gives a scalar quantity. Sometimes, a dot product is also named as an inner product. In vector algebra, dot product is an operation applied on vectors. The Scalar product or dot product is commutative.

## What is AXB XC?

(a x b) x c = (a c)b – (b c)a (1) for the repeated vector cross product. This vector-valued identity is easily seen to be. completely equivalent to the scalar-valued identity.

How do I prove that ax Bxc )) B AC )- C AB )?

Originally Answered: How do I prove that (A X (B X C)) = B(A.C)-C(A.B)? Imagine three vectors. Vector A=(Ax,Ay,Az). Put B on X axis，put C on XOY.So B=(Bx,0,0),C=(Cx,Cy,0).

### Why Axbxc and AxB XC are not the same?

Therefore, (A X B) X C ≠ A X (B X C), because there is an ordered pair in the first element of (A X B) X C and not for A X (B X C). Additionally, neither equal A X B X C, because this is a 3-tuple (3 elements) while the others were an ordered pair (2 elements).
