The Physics of Billiards
Newton's Laws

First Law: An object at rest stays at rest. If it is moving, the object will continue to move with the same velocity.

Second Law: The net force on an object is equal to the product of the objects mass and its acceleration.
(F = ma)
Once the cue ball begins to roll there are no net external forces acting in the two-ball system; therefore the a must be = 0. Acceleration is the rate of change of velocity. If acceleration is 0 there is no change in velocity. When the two balls collide the only forces acting are internal and they do not affect the net force. This means that the center of mass of the system continues to move forward with the same velocity and direction after the collision.

Third Law: When two objects interact, the forces acting on them from each other are always equal in magnitude and opposite in direction.
Collisions

Elastic: The Kinetic Energy of the system is conserved after the collision.
Ex. The collision of a cue ball with an object ball.
Head on: The Kinetic energy of the cue ball is transferred almost entirely to the object ball with a small amount of energy lost in sound.

The two object system is closed and isolated so linear momentum is conserved and the collision is elastic so the kinetic energy is conserved. The balls are equal in mass so:

m1v1i = m1v1f + m2v2f (linear momentum)

½ m1v1i2 = ½ m1v1f2 + ½ m2v2f2 (kinetic energy)

v1f = [(m1 - m2)/(m1 + m2)] v1i

v2f = [2m1/(m1 + m2)] v1i
If m1 = m2, the above equations reduce to v1f = 0 and v2f = v1i

Basically the cue ball is initially moving, stops suddenly when it hits the object ball at initially at rest which after the collision takes off with the initial speed of the cue ball.
After Collision
Rolling

A rolling object has two types of kinetic energy.

Rotational Energy: ½ Icomw2

Physics of Billiards Essay - Physics can be found anytime, anywhere. Billards is one game where the more you know about physics the better a player you will be. Some of the main physics principles in Billards are: Newton's Laws: 1st: An object in motion tends to stay in motion while an object at rest will stay at rest, unless acted upon by an outside force. 2nd: Force is proportional to mass times the acceleration. 3rd: For every action, there is an equal and opposite reaction. Conservation of Momentum: In an isolated system, (a system with no outside force acting upon it) then the total momentum will remain constant....   [tags: physics sport sports pool billiards] 382 words

Physics in Sports Essay - Physics in Sports Introduction Billiards, Pool or 8 Ball are the names given to this game. For many of us 8 Ball is a game that we play at friends' place or at pool houses, pubs and a good many other places. But when you are playing 8 Ball you would never really think about physics would you. But it is there, and it is in play everytime the cue hits the ball to make it curve, everytime you jump the ball over another or bounce it around the cushioned sides to get the white ball to connect with one of your own....   [tags: Papers] 1637 words

The Physics of the Arc Essay - ABSTRACT Several researchers have devoted efforts on studying physics of arc and descriptive models are used to explain many arc welding related phenomena. However, due to the subject complexity, doubts still emerge about the mechanisms of some phenomena related to the arc. For instance, the description about electromagnetic interactions with the arc, which governs the arc trajectory and lead to plasma jet and arc blow formation, seems to be yet controversial. Thus, the present study aimed a better understanding of these phenomena....   [tags: Physics ]

The Physics of Fishing Essay - The Physics of Fishing The use of a boat while fishing and some of the physics applicable to boating will be included in exploring the various ways physics applies to the sport of fishing. Other topics will include the fishing rod, fishing lure, casting, and the fish itself. The boat floats on the water according to Archimedes Principle which states an immersed object is buoyed up by a force equal to the weight of the fluid it displaces. The force applied downwards by earth’s gravity coupled with the upward force of buoyancy allows the boat to float....   [tags: Physics ]

Essay on The Physics of Roller Coaster - i: Introduction You apprehensively walk up the iron steps and onto the platform. You’re reluctant to go any further, but your friend eggs you on, saying, “It’s not that fast.” You step into the seat and pull the harness down over you. No, this isn’t the latest, greatest technological frontier. It’s a roller coaster. Since 1804 when the first wheeled roller coaster- called “Les Montagnes Russes”- was constructed in Paris, France, roller coasters have been a staple of adventure and fantasy among children and children-at-heart....   [tags: Physics] 1556 words

Essay about The Physics of Roller Coasters - A roller coaster is a thrill ride found in amusement and theme parks. Their history dates back to the 16th century. It all started in Russia, with long, steep wooden slides covered in ice. The idea then traveled to France. Since the warmer climate melted the ice, waxed slides were created instead, eventually adding wheels to the system. The first roller coaster in which the train was attached to the track was in France in 1817, the Russess a Belleville. The first attempt at a loop-the loop was also made in France in the 1850s....   [tags: Physics] 866 words

The History of Billiards Essay - There are many different theories as to when and how billiards was first developed. A lack of actual physical evidence has left most of these theories as simply speculation. Most people agree, however, that the game gained its roots from lawn games, which were not unlike croquet, played by nobility. Early players were said to include King Louis XI of France (King between 1461 and 1483); Mary Stuart, Queen of Scots (1542-1587); King Louis XIV (1643-1715); Marie Antoinette and her husband King Louis XVI....   [tags: essays research papers] 400 words

Applications of Physics For Different Industries Essay example - INTRODUCTION Physics attempts to describe the fundamental nature of the universe and how it works, always striving for the simplest explanations common to the most diverse behaviour. For example, physics explains why rainbows have colours, what keeps a satellite in orbit, and what atoms and nuclei are made of. The goal of physics is to explain as many things as possible using as few laws as possible, revealing nature's underlying simplicity and beauty. Physics has been applied in many industrial fields, which include the air industry, construction industry, automobile industry, manufacturing industry and many others....   [tags: Physics] 1954 words

Exact point at which slide becomes rolling: Vp= R*w

The harder you hit the ball, the farther it slides before the ball is rolling (depends on the initial velcocity and spin). The faster speed makes the ball slide farther before the friction in the surface causes natural follow.
