Conservation of Momentum: The principle stating that the total momentum of an isolated system remains constant before and after a collision.
A collision where kinetic energy is conserved, meaning there is no loss of energy during the collision.
A collision where kinetic energy is not conserved, resulting in some loss of energy during the collision.
