It was rated excellent and fun! Uses sliders to gather much data quickly. Direct link to Sophie's post Hello. In tables without optimal dynamics, a wider range of possibilities exists, which makes the full analysis of all possible paths impossible: A ball could end up bouncing chaotically in one part of the table forever, never retracing its path, but also never covering the whole table. 7foot pool tables measure 93 by 54 inches in length and 32 inches tall. Advanced pool players who know geometry will avow that the contact point is so thick on non-straight in shots that balls will be driven straight into rails. Puzzle 1.

And we're going to get Billiards from wolfram mathworld billiards and puzzles how to play pool like a mathematician geometry week 2 2007 dy dan. To play pool like a mathematician, use the law of reflection, which says that whatever angle the ball approaches the rail at is equal to the angle it will bounce off the rail at. The Billiard Ball Problem is a beautiful exploration of a situation both natural and novel. Otherwise, shouldn't it be referring to the other two supplementary angles? Since I like playing with Excel and trying to extend what it can do, I wrote a spreadsheet to represent the problem. Write an equation to express one quantity, thought of as the dependent variable, in terms The double reflection thing is insane. that's that distance.

Your email address will not be published. Have them make videos of the shots and then analyze them. The angles formed as the That is, the total momentum before the collision has to be the same as the total momentum after the collision. Many people swear by the ghost ball method, but this method is weak for pocketing balls and there is a lovelyalternative you can safely try. I think that having them draw the scenarios afterward is key. Firing for the contact point from cue ball center on most shots means you hit the shot too thick--but contact point aim works beautifully for most shots! So for example, this green circular wooden dowels, 1-1.5 inch diameter, to serve as cue sticks to hit the balls. This article has been viewed 368,788 times.
