Physics of Pool :: physics sport pool billiards

Physics is the science that allows us to understand the fundamental behaviors of the universe. It net beexplored at the macroscopic and microscopic levels, giving insight into the way objects interact. present we will take a look at how physics can be applied to the game of pool. Almost all of the differentaspects of pool can be explained through physics, and a better understanding of these fundementalprinciples can aid in performance playing pool. In the game of pool there ar sixteen balls, one cueball and fifteen physically identical numbered balls.While there are many interactions between all the balls on the table, in order to modify things we willonly look at the interactions between the cue ball and the first ball it strikes. These principles can beexpanded to evaluate the entire arranging of balls on the pool table.In order to evaluate the physics of pool, first the measurable values of the system must be collected. Parameter Symbol harborCue ba ll mass m1 1.6x10-1 kgCue ball radius r1 2.79x10-2mBall mass m2-m16 1.7x10-1 kgBall radii r2-r16 2.86x10-2 mCoefficient of friction k 0.027 astute these values the Motion, Work, and Energy can all be derived.The motion of the balls can be catagorized into two general catagories which are collisions and spin orrotation. Here the emphasis will be on collisions between the balls. The spin can have asignificant effect on the motion of the ball, but due to duration constraints and complexity of the science ofit it will not be addressed to much detail. An elastic collision between two objects is one in which the total energising energy (as well as total momentum) of the system is the same before and after the collision. (Physics for Scientists and Engineers) In a collision between the cue ball and some other ball, since the masses are so similar the resulting anglebetween the vectors of the balls is approximately ninety d egrees.
