There is also an amazing amount of physics involved in the bat-ball collision, and in the performance and behavior of the bat itself. My interest in the physics of baseball bats began in 1998 when I was setting up a laboratory experiment for my students and decided to have them look at the vibrational behavior of a youth baseball bat. Now, several years later, vibrational and acoustic analysis of softball and baseball bats has become my primary area of research. I have been able to correlate the vibrational frequencies of bat barrels to measured performance, and have signicantly contributed to an understanding of the trampoline effect in a hollow bat. In addition, my vibrational analysis of the bending modes of a bat has added to the understanding of perception and feel, including why some bats sting more or less than others.<\/p><\/blockquote>\n<p>tip o&#8217; the baseball cap to Skye<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Why wood bats &#8216;crack&#8217; and metal bats &#8216;ping&#8217; and much more.
