WebPractice set 1: Magnitude from components. To find the magnitude of a vector from its components, we take the square root of the sum of the components' squares (this is a direct result of the Pythagorean theorem): For example, the magnitude of (3,4) (3,4) is \sqrt {3^2+4^2}=\sqrt {25}=5 32 +42 = 25 = 5. WebMay 14, 2024 · Evidently, a vector projection/component is a vector and a scalar projection/component is a scalar. ... In a change of basis, a component is a scalar. In a force decomposition diagram in a physics text you might see components that are vectors. Or the components might be described by magnitude, i.e., scalars.
