Definition: Parallel Vectors. Two vectors \(\vec{u}=\left\langle u_x, u_y\right\rangle\) and \(\vec{v}=\left\langle v_x, v_y\right\rangle\) are parallel if the angle between them is \(0^{\circ}\) or \(180^{\circ}\).

In this explainer, we will learn how to recognize parallel and perpendicular vectors in 2D. Let us begin by considering parallel vectors. Two vectors are parallel if they are scalar multiples of one another. In the diagram below, vectors ⃑ 𝑎, ⃑ 𝑏, and ⃑ 𝑐 are all parallel to vector ⃑ 𝑢 and parallel to each other.
Given the vectors $v$ and $w$, write $v = v_\parallel + v_\perp$, where $v_\parallel$ is parallel to $w$, and $v_\perp$ is perpendicular to $w$: $a) \ v = (2, 3, -7) \ ; \ w = (1,-2,-5)$ $b) \ v = (-3, 1, 2) \ ; \ w = (8,5,-3)$
The parallel vectors are vectors that have the same direction or exactly the opposite direction. i.e., for any vector a, the vector itself and its opposite vector -a are vectors that are always parallel to a.
We saw that two vectors 𝐮 and 𝐯 are parallel if vector 𝐮 is equal to 𝑘 times vector 𝐯 for some scalar quantity 𝑘, where 𝑘 is not equal to zero. Finally, we saw that vectors 𝐮 and 𝐯 are perpendicular if the dot product of vectors 𝐮 and 𝐯 is equal to zero.
5 dni temu · When two vectors are parallel, the angle between them is 0 ∘ or 1 8 0 ∘. When two vectors are perpendicular, the angle between them is 9 0 ∘. Two vectors, ⃑ 𝐴 = 𝑎, 𝑎, 𝑎 and ⃑ 𝐵 = 𝑏, 𝑏, 𝑏 , are parallel if ⃑ 𝐴 = 𝑘 ⃑ 𝐵.
The vector product of two vectors is a vector perpendicular to both of them. Its magnitude is obtained by multiplying their magnitudes by the sine of the angle between them. The direction of the vector product can be determined by the corkscrew right-hand rule.
