Resumen de Stone Skipping Physics
As a boy I spent many hours skipping stones across the surface of the water on the shore of Lake Michigan. The challenge was to get as many skips or as much distance as possible. Zero skips was a bust. One or two skips was disappointing, three or four skips was mediocre, and six or more skips was exhilarating. The angle of the stone with respect to the surface of the water seemed to be critical. A large angle approaching 45° produced one large jump and perhaps one or two more after that. A smaller angle produced more skips and a longer run. However, too small an angle would cause immediate sinking. Fine tuning the skill of stone skipping was a captivating pastime. Today stone skipping has become both a recreational and a competitive sport.
