Physics Of Shooting Essay

Pool also known as billiards is more than just a game, there are many aspects of physics involved in this game, momentum is just one example. Different types of pool games exist, the most popular being eight-ball, in where one player attempts to knock all solid colored balls into the pockets while the other player knocks in the striped balls into the pockets, and players the players attempt to know in the eight ball last. Physics is the study of motions and collisions of large objects. Pool is a great visual example of physics in action. With pool you can begin to study how movement of pool balls are driven by momentum and collisions, you can then apply formulas and apply them to your everyday game. By learning these theories and how they work

Momentum is conserved which means that the initial momentum must equal the final momentum of an object. Momentum is seen when playing pool when the pool balls collide into each other. Momentum can be found using the following equation, p=mv, p = momentum, m is the mass, and v is the velocity. When the pool balls collide into each other the collision is almost perfectly elastic, an elastic collision is when kinetic energy is conserved before and after the impact of the objects, in this case the pool balls. Kinetic energy is the energy that is associated with the motion of an object. In order for there to be an elastic collision between the two pool balls their total kinetic energy must be the same before and after the

Sliding, rolling, and spinning of the pool balls have to be taken into account. Friction of the pool table surface could allow for irregularities, which would make calculations difficult. A small amount of friction comes from air resistance, the main source is from inside the balls themselves. So when friction comes into play the balls are forced into an inelastic collision, in this collision the kinetic energy after the collision is less than the kinetic energy before the collision. This happens because the balls are not perfectly elastic, they can't escape the effect of friction, and because of the conservation of energy the total amount of energy stays the same. As the balls are compressed and return to their original shape, the friction between the molecules inside the ball converts the kinetic energy into
