How do you know if a dot product is parallel?

Perpendicular, because their dot product is zero. Explanation: Two vectors are perpendicular if their dot product is zero, and parallel if their dot product is 1. Thus our two vectors are perpendicular.Click to see full answer. Furthermore, what happens if two vectors are parallel?If two vectors are parallel, then one of them will be a multiple of the other. So divide each one by its magnitude to get a unit vector. If they’re parallel, the two unit vectors will be the same. Edit: Someone pointed out in the comments that two vectors are still parallel if they point in opposite directions.Additionally, what does it mean if dot product is 1? If you already know the vectors are pointing in the same direction, then the dot product equaling one means that the vector lengths are reciprocals of each other (vector b has its length as 1 divided by a ‘s length). Moreover, what does dot product tell you? The dot product tells you what amount of one vector goes in the direction of another. For instance, if you pulled a box 10 meters at an inclined angle, there is a horizontal component and a vertical component to your force vector.What is dot product example? Example: calculate the Dot Product for: a · b = |a| × |b| × cos(θ) a · b = |a| × |b| × cos(90°) a · b = |a| × |b| × 0. a · b = 0.
