Elastic collision is always a great word to know.
So is gobo. Does it mean:
a calculus or concretion found in the stomach or intestines of certain animals, esp. ruminants, formerly reputed to be an effective remedy for poison.
a screen or mat covered with a dark material for shielding a camera lens from excess light or glare.

Science Dictionary
elastic collision   (ĭ-lās'tĭk)  Pronunciation Key 
Physics
A collision between bodies in which the total kinetic energy of the bodies is conserved. In a perfectly elastic collision, no energy is dissipated as heat energy internal to the bodies, and none is spent on permanently deforming the bodies or radiated away in some other fashion. Elastic collisions, such as the collision of a rubber ball on a hard surface, result in the reflection or "bouncing" of bodies away from each other. Comapre inelastic collision.
