What is Physics of Sports video?

The Physics of Sports video is a 3-5 minute video detailing the physics of a certain sports action. Our group choose to do throw and catch of a lacrosse ball.

What was our process?

First, we brainstormed ideas for our project. In the end we were deciding between a fishing cast and a lacrosse throw. We choose the lacrosse throw because we figured it would be more relatable to the general public. Next we created a 15 part storyboard to detail every scene of the video. After that we typed up a script to go with every scene. This gave us a clear look at what we were going to say and film. Next we filmed. We filmed on the football field and had Mahalia, one of our group members wear her uniform. Filming took place over two days. After filming we went on to calculations. We found the vertical, horizontal and final velocity of the ball. We also found the force needed to catch and throw the ball. After doing the calculations, I sent Rory, my other teammate, the video clips and he edited them together on his home computer. We choose to do this because Rory had installed a editing software called Premiere Pro. After that, we went into a quiet space and recorded voice audio. The day the project was due we had a little bit of a problem. Rory's computer has crashed and deleted our entire video. Thankfully out teacher, Mr. William was kind enough to give us more time to re-edit the video. The following Tuesday, we showed our movies in the annual STEM movie festival. It was a great experience because I got to see other STEM students projects.

here is the link to our video

Vertical velocity

Vertical velocity is an object's movement and speed in the up and down direction. In our project, vertical velocity was used because we wanted to know the ideal angle to throw a lacrosse ball at. The formula is 9.8 m/s (Tfall).

Horizontal velocity

Horizontal velocity is an object's movement in the side to side direction. In our project we used horizontal velocity to find the average speed a womens lacrosse pass is thrown at. The formula is dh/Tair. After filling in the formula we got 11.26 m/s.

Total velocity

Total velocity is found by using the Pythagorean theorem. To do this you must square both horizontal and vertical velocity. Add them together, and take the square root of the sum. After doing this we found that the total velocity was 12.97 m/s.

Force of Impact

The force of impact is how much force a certain object has when it collides with a specified object. In our video, we found force of impact by using the equation ft=mv. The force of impact of catching the lacrosse ball was 9.26 newtons.

Reflection

In comparison to my first project I believe that I made many improvements as a team member. For example, I feel that I did a great job of keeping my group on task. I made this my priority because in this project we had a much shorter deadline, which gave us no time to mess around. The second aspect of my group work that I think that did well on was the fact that I kept a positive attitude when our whole entire project was deleted. This was crucial because helped keep the group from giving up and making a mediocre video. Instead, we kept pushing and made the best video possible. One thing that I would like to work on is my editing skills. If I knew how to edit a video to high quality, then we would not have lost the video the day it was due. I would also like to become better at filming. This is because I want to be able to make a video look professionally-shot when it was really shot and edited on my phone.
