An important use of the dot product is to test whether or not two vectors are orthogonal. Two vectors are orthogonal if the angle between them is 90 degrees. Thus, using (**) we see that the dot product of two orthogonal vectors is zero. Conversely, the only way the dot product can be zero is if the angle between the two vectors is 90 degrees ...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. It even provides a simple test to determine whether two vectors meet at a right angle. 1. Adding →a to itself b times (b being a number) is another operation, called the scalar product.

For two vectors lying on a plane, it is a bit easier to visualize. Notice that if θ = π/2 θ = π / 2, then the dot product is 0 0, so ...A dot product between two vectors is their parallel components multiplied. So, if both parallel components point the same way, then they have the same sign and give a positive dot product, while; if one of those parallel components points opposite to the other, then their signs are different and the dot product becomes negative.The dot product of vectors A and B results in a scalar given by the relation . where is the angle between the two vectors.
