"About one-third of the original bat-and-ball energy is carried off as kinetic energy in the flight from the bat and the rest of it (about three-tenths of the original total energy is lost in friction in the course of the distortion of the ball--and then in heating of the ball. (Indeed, if you catch a Mark McGwire blast in the bleachers, you might be able to sense the side of the ball that he hit from its slightly increased temperature.)"
How cool is that? When a batter hits a ball, it actually heats up where it comes in contact with the bat in the transfer of energy from bat to ball. I mean, really, who thinks about these things? I certainly didn't! But I will now.
This book is blowing my mind. I love it! I don't care if I am a geek, nerd, dork, whatever--physics is fascinating.
