WebSep 21, 2024 · Add a comment. 5. Pressure is a scalar because it does not behave as a vector -- specifically, you can't take the "components" of pressure and take their Pythagorean sum to obtain its magnitude. Instead, pressure is actually proportional to the sum of the components, ( P x + P y + P z) / 3. The way to understand pressure is in terms of the ... WebAug 11, 2024 · Equation 3.2.2 is a scalar equation because the magnitudes of vectors are scalar quantities (and positive numbers). If the scalar α is negative in the vector equation Equation 3.2.1, then the magnitude →B of the new vector is still given by Equation 3.2.2, but the direction of the new vector →B is antiparallel to the direction of →A.
