Physics of Baseball

David KaganDavid Kagan, CSU Chico

All of David’s material related to the Physics of Baseball are available on his website:

David demonstrated the Physics of the Baseball bat including the progression of the baseball bat. He explained how to find the center of percussion of the baseball bat as well as the center of vibration.  The “sweet spot” of a bat is where the center of percussion and the center of vibration meet which means that the player will minimize the jarring force of the bat. David showed us many high speed videos from the playoffs that show the compression of a baseball bat being hit and the reaction of the bat after the impact. David demonstrated his rubber bat that has no internal support so that it can create a standing wave. By putting together that information, your students can choose the correction direction that the bat will swing and even guess where the baseball will break if it is outside or inside of the sweet spot.

Pablo shared the physics of the splash hits in the San Francisco Giants Stadium. The ballpark has been designed for maximum home runs and the majority are hit to right field, where the ballpark meets the bay. He discussed the geometry of the park and where a home run is most likely hit.

He has more materials on the change in velocity of a ball hit on different planets, the Physics of a home run, etc. Visit his website for additional materials and videos.
