Homework Help: The magnitude and the resultant vector

  1. Mar 5, 2008 #1
    Hi everyone,

    Could someone please tell me if the magnitude is the same thing as the resultant vector? I know how to solve for the magnitude, but isn't it the same thing as the resultant vector A+B?

    Thank you very much

    Yes, it is the same thing.

    Magnitude is defined as a scalar value having physical units.

    so for example, if a car's velocity is 12m/s [east]

    then 12 would be its magnitude.
