Qualitatively, it certainly seems the closest to an "actual" break. Of the models listed here, the intial Hertz-based model is probably the most accurate. Pull the rack back again so that the apex ball is aligned with the foot spot and the base is parallel to the back of the table. Push your fingers into the rack under the bottom row of balls, and then slightly push the rack forward. We cannot control or correct problems with third-party sites, but please let.

While the simplicity of this behavior is appealing, I would guess that "real" billard balls do not have such a stiff force response. Roll the rack up and down to ensure that it is packed tightly. Check out American Heritage Billiards full selection of pool cue racks and accessories.

Here is an animation of the forces:Īfter that, the corner balls and the cue ball shoot out, and the remaining balls continue to collide gently for the next millisecond or so. Almost all of the energy has moves to the back corner balls in the first 0.02 milliseconds. As you might expect, most of the energy in this case is transferred very quickly at the beginning of the collision. This seems like good evidence that above 1st-thought behavior is indeed the limiting behavior in the case where the stiffness goes to infinity. The 8 - ball will be pocketed about 10 of the time ( i.e. Here is a picture showing the forces, with each force vector emanating from the point of contact. Rack the 14 balls without the final ball if it does not fall within the rack, leaving the top position open. rack is solid, the 8 - ball moves significantly when the second ball is hit squarely. The two balls in the back corners shoot away along rays parallel to the two sides of the triangle. The force between two balls is given by the formula $$F \ =\ \begin $$Īs you can see, the result is very similar to my first thought:.

The cue ball has a initial speed of 10 units/sec. Part of the series: How to Play Billiards.Each ball has a mass of 1 unit and a radius of 1 unit.

All balls are assumed to be perfectly elastic and almost perfectly rigid.

This break was computed in Mathematica using a numerical differential equations model. Note: Mathematica notebook is attached at the end of this post and also is available on my web page.
