B is for Boomerang, Bernoulli, and Bowie

What does center of gravity have to do with a boomerang? As the Asher GT 9-12th found out, everything!! On September 27th, Mr. Bowie, a physics teacher originally from Putnam City HS now with the State Department of Education, presented a most interesting lecture on why the boomerang flies. We found out center of gravity and gyroscopic motion are essential to the aerodynamics of a boomerang. Bernoulli's principle states, as the velocity of an object increases, the pressure of that object decreases. Of course, it's inversely proportional. Also significant is the fact that the center of gravity of an object does not have to be physically part of the object. Probably the best part of all of this, Mr. Bowie shared all of this information long distance from OKC via Skype. Here is our 29 minute video. Notice the students taking notes on their iPads. Truly a 21st century classroom!!
