If energy were conserved in each collision, what would you expect the ratio of the total kinetic after the collision to the total kinetic energy before the collision to be? Are there anyof your collisions where energy is not conserved? Is this expected? Are there any collisions for which energy is conserved? Is this expected? You will probably find there is some energy loss in every collision. If this amount is asmall percent of the initial kinetic energy, the collision can be considered to benearly elastic. Based onyour calculations, which of your collisions were elastic or nearly elastic? Which were inelastic?
