Web24 de ago. de 2024 · In general, F = F ˆF, where F is the magnitude of F, and ˆF is the unit vector pointing in the direction of F. Solving equation (2.5.1) for ˆF gives the approach to … WebEquation 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 2.1, then the magnitude B → of the new vector is still given by Equation 2.2, but the direction of the new vector B → is antiparallel to the direction of A →.
