Physics of Pool :: physics sport pool billiards

Physics is the science that allows us to understand the fundamental behaviors of the universe. It back tooth beexplored at the visible and microscopic levels, giving insight into the way objects interact. Here we will take a look at how physics can be applied to the naughty 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 compete pool. In the game of pool there are sixteen balls, one cueball and fifteen physically identical numbered balls.While there are many interactions among all the balls on the table, in order to simplify things we willonly look at the interactions in the midst of the cue ball and the first ball it strikes. These principles can beexpanded to evaluate the entire system 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 Va lueCue ball 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 0.027Knowing these values the Motion, Work, and Energy can all be derived.The motion of the balls can be catagorized into two worldwide catagories which are collisions and spin orrotation. Here the focus will be on collisions between the balls. The spin can have asignificant pith on the motion of the ball, but due to time 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 kinetic 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 another ball, since the masses are so similar the resulting anglebetween the vectors of the balls is approximately ninety degrees .
