Accelerometers and Great America: Here’s your ‘permission slip’

Last year, after more than a decade of bringing students (and their accelerometers) to Great America, Phillip Becker of Saint Helena High School was shocked to be informed by park staff that students would not be allowed to bring their accelerometers on the rides. Disappointment ruled the day, but his students made the best of it. Upon returning to school, Mr. Becker typed out a to-the-point letter to Cedar Fair Entertainment Company (the parent company for Great America), expressing his outrage at this change in policy. Shortly thereafter, Cedar Fair Entertainment replied, with a letter notifying him that there had…

Physics of Baseball

David Kagan, CSU Chico All of David’s material related to the Physics of Baseball are available on his website: Phys.csuchico.edu/baseball 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…

Fall 2012 Conference Share ‘n Tell

Tom at Share n TellTom Woosnam, Crystal Springs

Tom showed us a conducting experiment (picture to come) with two cans and a two copper wires that do not touch and attach to a coup of water. After the cup of water is filled a small neon bulb that that is connected to one of the two copper wires can discharge repeatedly. Tom’s best guess as to why it flashes is that one of the metal cans becomes randomly charged, say negatively, and that negative charge travels up the conducting materials to the water and repels electrons through the other wire to the other side that builds up potential.
