Muller, H. R. [2], on the Euclidean plane E-2, introduced the one-parameter planar motion and obtained the relation between absolute, relative, sliding velocities (and accelerations). Also, Muller, H. R. [6] provided the relation between the velocities (in the sense of Complex) under the one-parameter motion on the Complex plane C = {x + iy vertical bar x, y is an element of R, i(2) = -1}.
