DIAZ-SOLORZANO, S.  e  GONZALEZ-DIAZ, L.A.. Un tratamiento alternativo para el análisis de la colisión elástica bidimensional no relativista entre dos esferas rígidas con parámetro de impacto dado. Rev. mex. fís. E [online]. 2009, vol.55, n.1, pp. 57-60. ISSN 1870-3542.

We present a novel treatment for the calculation of the velocities after a two-dimensional elastic collision of two rigid spheres with impact parameter given. For that, we define the collision vector which is invariant under Galilean transformations. The vector gives an alternative form of Newton's collision rule.
