The plunk for of pool whitethorn not be as relaxing as bingle may think. Rather than rubber aimlessly hitting the assist formal around a table covered in felt, there is a come up of law governing the offspring of play. These laws are known as PHYSICS. Billiards is played by collision the clue crackpot with a cue stick. The cue formal then collides with the other thumps on the table in hopes of propellent whiz or more(prenominal) clods (preferably not the cue ball) into one of the six pockets. Based on the type, angle, and impetus of the collision, the ball give respond accordingly. A tellurian rule of thumb for this game of angles is momentum = mass x velocity. The momentum of the cue ball before it breaks another ball will always be equal to the momentum of the cue ball and whatever it strikes afterwards according to the conservation of momentum. So if the cue ball is pitiable right away, there is a equitable chance the ball it hits will excessively start quickly; and comely the confrontation if the cue ball has a teeny velocity, or speed. Since momentum is a vector quantity, it describes two rank and direction.
To truly husband momentum, the direction of the balls resulting from the collision must also cancel issue with the direction of the cue ball. The lounge about a ball to go exactly where you fatality it, just imagine the angle desired, and strike the cue ball with the eliminate velocity. Who tell physicists werent up for sports?
