Week 4: Collisions, Elastic collisions, Inelastic collisions
Collisions conserve momentum and energy: the total momentum and energy of the colliding particles after collision are equal to that before collision. Electrons and fully stripped ions possess only kinetic energy. Atoms and partially stripped ions have internal energy level structures and can be excited, de-excited, or ionized, corresponding to changes in potential energy. It is the total energy, which is the sum of the kinetic and potential energy that is conserved in a collision.
