The additive property of charge is not an obvious property It is related to the fact that electric charge has no direction associated with it charge is a scalar 6 Charge is not only a scalar or invariant under rotation it is also invariant for frames of reference in relative motion This is not alway true for every scalar For example kinetic energy is a scalar unde rotation but is not invariant for frames of reference in relativ motion
