THE PHYSICS OF ARCHERY
We chose archery because we wanted to find the how much force the arrow released on impact.
The first thing we did to start our idea-movie, was come up with a story board. Francesca drew out 6 frames, which we all ended up redoing and editing. We had assigned tasks for each of us to bring something from home to use for the movie. We had eventually gotten arrows, food, a bow, a wig, and some boxes to fire at. After that, we had decided that Francesca would direct, Maddie would calculate, I would act, and "Rodrigo would edit". Eventually the roles were switched and Francesca was the director and editor, and Rodrigo was the cameraman and box boy.
Our original plans for the film was supposed to be 5 minutes long, but we had didn't have enough film to have it that long so we improvised with bloopers but that still wasn't enough.
In the end we learned somewhat how to edit and had all the facts and physics at the end. Then we added a clip from the Hunger Games to show what we were modeling after, however it was a different scene than the one we were filming.

We used a tape measurer to find the approximate distance of the place where the arrow was shot to the area of the boxes. We got 17.22m, which we later used with the time for the arrow to get to the other side, 0.01s, to find the velocity. Velocity is the change in distance over the change in time.
We then found the work, which uses Joules as its unit. As explained in the first paragraph, the formula for work is force multiplied by the distance. The work we found was 861 Joules on the bow. As we found the Kinetic energy to be 4.6 Joules, the Potential energy is also 4.6 Joules. Potential energy is always equal to Kinetic energy.
The distance from which the arrow was shot to were it landed was 17.22m. It took 0.01 seconds for the arrow to travel the 17.22m. I pulled back on the arrow with a force of 15N on the bow. The force of when the arrow hits the boxes is 309.68N. We found the work of the bow, using the formula force x distance, the work of the bow is 861J. We found the velocity using the formula distance/time. We got the velocity of the arrow to be 17.05m/s. And we found the kinetic energy of the arrow using the formula KE=1/2mv^2 and the kinetic energy of the arrow is 4.6J. Using a spring scale we measured the force being exerted on the box. The force was 50N.
We wanted to find the force of the bow string as it released the arrow, so we used a spring scale. This worked much like finding the mass or newtons of a weight, but since it was diagonal, there could have been lots of human error. We found that the force was around 50N on the bow string.

I think that there were somethings that worked and didn't work. The things that worked was the amount of time we had to film and the amount of space we had. However what was difficult was that our group wasn't that great at editing so we all had to spend several hours learning how. I still barely know how to edit anyways so that's a minus. I think two things I learned was that editing is a very complicated thing to do and that the longer time you put into editing the better quality the movie will be. Another thing I learned is that you should always bring the supplies on the second day and not the fourth.
