Collision Types
Most text books describe three different types of collisions. In reality, it is more true to say there are two ends of a spectrum (range) of collision types. Regardless of what type of collision occurs, the total momentum of the system will always be conserved if there are no external forces present.

Remind yourself that for any of these collisions, the total momentum of the closed system remains the same and the total energy remains the same (it just may change form from KE to heat). Both the Momentum and the Energy are always conserved when dealing with a closed system.
One example of the different types of collisions comes from examining bullets striking blocks of wood.

running into 3 blocks of wood with equal mass.
