WebSep 19, 2024 · When It is multiplied with a vector it changes the vector's magnitude because it only has magnitude but no direction. So then why a negative scalar rotates a vector's direction by 180 degree? For example, if the scalar is -5 then it will scale the magnitude 5 times and also rotate the vector by 180 degree. Thus it changes the vector's direction. WebAnswer (1 of 3): If the angle between two vectors is acute, then their scalar product (also called dot product and inner product) is positive.
