When calculating vector magnitude, a negative component is squared, which results in a positive value. This ensures that the direction indicated by the negative sign (e.g., downward or leftward) does not reduce the overall length of the vector.
Conditions: The vector has real components in a Cartesian coordinate system.; The magnitude is computed using the Euclidean formula x2+y2.

The vector magnitude formula uses the square root of the sum of squared components because it is a direct application of the Pythagorean theorem. When a vector is drawn in a Cartesian plane, its horizontal and vertical components form the legs of a right triangle, and the vector itself is the hypotenuse.
Conditions: The vector is represented in an orthonormal Cartesian coordinate system.; The components correspond to perpendicular displacements.; The magnitude is the Euclidean length of the vector.

To find the magnitude of a vector from its components, you calculate the square root of the sum of the squares of those components. This process effectively measures the Euclidean length of the vector in the coordinate plane.

The Pythagorean theorem can be used because the perpendicular component displacements of a vector in an orthonormal Cartesian plane form the two legs of a right triangle, with the vector itself acting as the hypotenuse. The theorem relates the lengths of the legs to the length of the hypotenuse, allowing the calculation of the vector's magnitude (length).
Conditions: The coordinate axes are perpendicular (orthonormal).; The vector is drawn from the origin to its terminal point.; The magnitude is the Euclidean length of the vector.
