Recently the iPhone game 8-pool has gained popularity as friends compete back and forth and there iMessage. Basically the game is a virtual version of billiards, and as result there is plenty of physics behind it. For one thing, because this game is virtual, friction of air resistance is non existant. Furthermore, while conservation of momentum is always conserved, in this game energy is also conserved between balls. The energy lost to sound and heat is not a factor, and therefore all energy is transferred into mechanical. Lastly, principles of conservation of linear momentum are present and shown as when you line up to hit a ball, it shows the resulting direction of the ball and the cue ball. These two directions will always form an angle of 90°, illustrating the principle of pool balls conserving momentum in both the x and y directions.

Thanks for discussing conservation of angular momentum between the balls as they role, great job.
