EM Research Group Scalar vs. Vector Quantities Ö Defined by magnitude and direction Ö Must define a set of laws analogous to those for scalar quantities Ö Examples: Force, velocity, electric field, and magnetic field Ö Completely specified by a single number along with a given dimensional unit Ö Obeys usual algebraic laws (e.g. addition, subtraction, multiplication, and division) Ö Examples: Mass and charge 1 P 2 P 12 12 d d r r = Note: Sometimes vectors are denoted by an arrow above the symbol, sometimes by a line, and sometimes with a bold font. We will use both for presentation clarity.
