  In this paper, we investigate the scattering of two $\phi^6$ kinks and derive
the real dynamics by solving the appropriate field equation numerically
employing a Runga-Kutta method. We also use a collective coordinate
approximation to find approximate dynamics, with the objective being to compare
the approximate motion to the real dynamics in order to test the validity of
this kind of approximation, which is used extensively in the study of solitons.
