Over the last 3 weeks, I have had the honor of working on the physics of volleyball not only with 3 amazing volleyball players, but also fabulous people and friends. I could not have asked for a better, more productive group. To the many, many selfies to the hours of volleyball footage, this group of girls have conquered the physics of the sport of volleyball.
Our Project:
We were asked by the San Marin athletic director to create a video that explained the physics of a sport, and tips on how to make that sport better so San Marin can have the best sports teams that we possibly can. We started off the video by an intro of each of our names and then explaining that our main focus of the video was the pass. Then, we each had a slow motion video of us passing, to show the correction form you should have when you pass. Then there was a video of Katie and I peppering (passing, setting, and hitting) to show the pass in a more game-like situation. Then we started to explain the physics of the pass, that are explained below. Then we had Katie give tips and tricks on how to pass including passing with your legs at a 90* angle, and having your arms 4 meters off the ground when you finish the pass. After we say thank you for watching, we lightened up the mood of the video by showing bloopers of the video including annabel hitting her head and Julia squatting for her 45* angle pass.

Physics:
Velocity of the Ball:
v=d/t v=5m/1.66s v=3.012m/s
Velocity of Arm:
v=d/t v=0.4m/0.1s v=4 m/s
Elastic Collision
v=7.012m/s
Horizontal and Vertical Velocity of the Ball:
a^2+b^2=c^2 x^2+x^2=7.012m/s^2 x=4.95m/s
Height of the Ball:
d=1/2at^2 d=(9.8m/s^2)(1.66s)^2 d=13.5m
Work your arm does:
w=1/2mv^2 w=1/2(0.4026kg)(3.012m/s)^2 w=1.8262J
w=fm 1.8262J=5m(F) f=0.3652 N
Reflection:
During this project we had many ups and down. We had a lot of trouble figuring out how to measure certain things that we need such as time and distance, so we solved that by just taking several trials and averaging them out. We also had trouble with editing. At one point, we accidentally pressed the wrong button and erased everything halfway through, so we had to restart everything so it did not turn out exactly the way we wanted it. We did really well at working together though, and working very fast and efficiently. When we had to start from scratch with only half the time left, every group member became a large contributor and did their best to help. If we were to do this project again, I think we should've used up less time with introductions and bloopers and had a more straight to the point video.
