Welcome to Physics Friday! I would be happy to receive suggestions for future topics based on questions YOU have relating to Baseball and science/physics/mechanics: you can drop them in the comments below or reach me at michael@btoolbox.org . As mentioned by everyone from Dr. Alan Nathan on Twitter to Ben on the latest episode of Effectively Wild, the sweltering temperatures in Los Angeles during Games 1-2 of the 2017 World Series might very well have contributed to enhanced distance on a few home runs that otherwise would have found gloves or grass. Probability of HR increases by 20%, on average, when temp increases from 70 to 90 deg, all other things equal: https://t.co/xRLBHDmIzC — Alan Nathan (@pobguy) October 26, 2017 Using the same approach I employed in an earlier post on FanGraphs Community Research , let’s consider how the dimensions of Dodger Stadium could be “scaled” in different meteorological conditions. I had previously done this analysis when comparing the warm, dry March conditions in Cactus League spring training games compared to the cool, humid April conditions most teams will experience at their first few games of the regular season. Air expands at higher temperatures, decreasing density. A ball traveling through warm air will have to push fewer air molecules out of the way of its path (molecules that cause drag on the ball in flight ) than a ball traveling through cold/dense air. As a simple way of accountin ...
