# 3 Elastic collisions in one dimension

In this section you will examine the outcomes of various elastic collisions in one dimension. These are essentially particular cases of the general elastic collision described by Equation 1 and Equation 2. Cataloguing one-dimensional elastic collisions may sound like a rather esoteric pastime, but as you will see, you have probably witnessed many collisions of this type, and may even have paid handsomely for the privilege.
