DO IT BETTER: Physics of Sports

Copy of Copy of Physics of Swimming.mov

My group all really enjoyed  doing the Physics of Sports videos so we decided for the Do It Better project to create a new and better video where we go more in depth and specific video.  Another thing we all had in common is that we all love swimming and have  done it for multiple years so we decided to make our video on swimming and how to improve swimming through physics.  First we had to story board we all put our heads together and came up with a really bad swimmer and then a coach for that swimmer who would help him in the water and then in  the classroom.  By combing both of these we want to split up when we do the physics so its not just one long boring equation section.

First step was throwing together a story board to follow for the filming and then later for the editing. After we made the story board we all went down to a local pool to start filming.  We followed the story board we had made and shot scenes of an interview, of dives, of non hydro dynamic vs. hydro dynamic swimming, and flip turns. Then the next day at school we filmed the physics portions in a classroom where we had access to a whiteboard to write out and explain the equations. Then the rest of the time inperson we spent on editing and perfecting the video so it would be striaght forward, to the point, and good quality.

F = ma

Force = mass * acceleration

D = .25pAv^2

drag = .25density * crosss section of body * velocity squared

P = mv


momentum = mass * velocity

To get the physics numbers and variables we watched back the videos we took of the dives, swimming, and flip turns.  Then we researched the equations that would make sense to calculate and compare numbers from bad swimming to good swimming and show with those equations  how to improve purely through the physics but then also through the actual skill  in the video.
