( θ). Other times we need not the parallel components but the perpendicular component values multiplied.The Dot Product of Vectors is written as a.b=|a||b|cosθ. Where |a|, |b| are said to be the magnitudes of vector a and b and θ is the angle between vector a and b. If any two given vectors are said to be Orthogonal, i.e., the angle between them is 90 then a.b = 0 as cos 90 is 0. If the two vectors are parallel to each other the a.b =|a||b| as ...V1 = 1/2 * (60 m/s) V1 = 30 m/s. Since the given vectors can be related to each other by a scalar factor of 2 or 1/2, we can conclude that the two velocity vectors V1 and V2, are parallel to each other. Example 2. Given two vectors, S1 = (2, 3) and S2 = (10, 15), determine whether the two vectors are parallel or not.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.

The projection of a vector b onto a ...The dot product of two normalized (unit) vectors will be a scalar value between -1 and 1. Common useful interpretations of this value are. when it is 0, the two vectors are perpendicular (that is, forming a 90 degree angle with each other) when it is 1, the vectors are parallel ("facing the same direction") and;Both the definitions are equivalent when working with Cartesian coordinates. However, the dot product of two vectors is the product of the magnitude of the two vectors and the cos of the angle between them. To recall, vectors are multiplied using two methods. scalar product of vectors or dot product; vector product of vectors or cross productThe dot product of parallel vectors.
