In this project, we had seven work days to make a video explaining the physics behind an overhand volleyball serve, and how to succeed in performing one.
When making of this video, we started by brainstorming several ideas of what sport to do in our video, and we concluded that we would demonstrate an overhand volleyball serve. We then proceeded to create a storyboard for our video on Storyboard That, an online storyboard website. After that, we typed a script, recorded our video, and made our physics calculations.
While brainstorming, we came up with multiple possibilities, including soccer kicks, football passes, etc. We made our final decision on an overhand volleyball serve, one of the key skills to know in volleyball. The next step was storyboarding. The website we used to create our storyboard was storyboardthat.com. On this program, you can create storyboards with descriptions, notes, and graphic representations. We took a few days to work on storyboarding our video, and then moved on to the next step, scripting. The earliest lines of our script were created at the same time as our storyboard, but our point of focus shifted over to the script after we completed the storyboard. It took us about two days to write our script. We recorded most of our video in the next two days, however we did the finishing touches on the last day. We recorded in various places around the San Marin High School campus. The physics calculations in our video were mostly made with our script, but we added in a few concepts in the last few days.
We calculated that the horizontal velocity of the volleyball to be 15.65 meters per second (35 mph), and the vertical velocity was 2.94 meters per second (6 mph). Horizontal and vertical velocity are the speed of an object moving horizontally or vertically. Put the two together and you get a parabolic line. We discovered that a good serve should have the ball going about 0.6 meters above the net, or 2.8 meters above the ground. Then to find the force required to make the ball difficult to receive, we used the equation mv=ft (mass* velocity= force* time). We set it up as 0.27 kg(15.65 m/s)= X(1/120 of a second) and calculated the force of 505n, or 114 lbs. If the time the hand touches the ball decreases, the force applied increases.
Overall, I think my group worked very well together. We cooperated and and collaborated with each other, making the task more easy to accomplish. We also listened to each other's ideas, and applied them to the project. One thing we could've improved on was organization. At some points of the project we were all uncoordinatedly working on pieces of the project, sometimes even pieces that had already been done. We also could have improved on productivity. It took us about half an hour just to choose the music for our video. All together though, I think we had a very successful physics of sports video.
