Worked example for momentum and perfectly elastic collisions.  Shows how to determine the final velocity of two nuclear particles when one is in motion and the second particle is at rest. After the collision each mass has a different final velocity.

This problem uses conservation of momentum and conservation of kinetic energy to determine the final velocities.

In an inelastic collision the objects stick together. Due to deformation of the objects, the release of heat and increased vibrational energy, kinetic energy is not conserved.  Momentum is conserved. In a perfectly elastic collision the objects do not stick together, therefore kinetic energy and momentum are both conserved.
