Softer hits will generate more throw at impact. There are 11 references cited in this article, which can be found at the bottom of the page. Intermediate and advanced pool players use The Law of Reflection. The law says a ball will bounce off the side of the table (the rail) at the same angle at which it hits the rail. The infinitely varying relative positions of these three elements are what create the countless shots we face throughout our playing years. This week, Im looking at three of my favorite secondary geometry textbooks. 1st of December, 2014 Pool table write up final draft Overview. to the longer side that's not the hypotenuse When do i use one or another?

Direct link to kubleeka's post It doesn't matter. Pool experts use all 17 dots, the imaginary 18th dot plus each of the pockets as a geometric way to divide the table. 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. Have them make videos of the shots and then analyze them. l`l6YH2*."dVeeA-0dfI30L^ $yf/H`q>0#aJ$Qf"L` d `{S1F2?d^@3)yS#p{g`L8 _ Ea.X The math says the ball goes in the hole every time, but practically thats not true.
