To find the length of a vector, simply add the square of its components then take the square root of the result. In this article, we’ll extend our understanding of magnitude to vectors in three dimensions. We’ll also cover the formula for the arc length of the vector function.
Vectors. This is a vector: A vector has magnitude (size) and direction: The length of the line shows its magnitude and the arrowhead points in the direction. Play with one here: We can add two vectors by joining them head-to-tail: And it doesn't matter which order we add them, we get the same result:

Vectors are geometrical or physical quantities that possess both magnitude and direction in which the object is moving. The magnitude of a vector indicates the length of the vector. It is generally represented by an arrow pointing in the direction of the vector.
24 Οκτ 2023 · How to Find Length of a Vector. The length (or magnitude) of a vector represents the size or amount of the vector irrespective of its direction. It gives you an idea of "how much" of the vector there is. The length is always a non-negative scalar value.
Basic relation. The length of vector | a | in Cartesian coordinates is the square root of the sum of the squares of its coordinates. Vector length formulas. Vector length formula for two-dimensional vector. In the case of the plane problem the length of the vector a = {ax ; ay} can be found using the following formula: | a | = √ ax2 + ay2.
Kids learn about basic vector math in the science of physics. How to add vectors using the head-to-tail method and the Pythagorean theorem. Example problems and the commutative and associative laws.
