We made a video about physics
Of course, if we just made it about random physics, then it would be kind of pointless to any audience except for people who love learning about physics and mechanical advantage. And of course many people get bored learning that at school. So to make things more interesting, everyone made a video with 3 other people that referenced the physics of a certain sport. We chose mountain biking.
First of all: Jordan has a really cool bike.
Now that that statement has gotten out of the way, I had better explain a little about the video. I helped do the research for the video and I gave some advice about the editing here and there. While researching, I found out some things that are important for any bikers, and they were put in the video. One example of something I found out was posture. Proper posture has you head about 15º relative to the ground. Your body should be 90º relative to your hands while on your handlebars.
Obviously there are some things we could have done better, such as not having an echoey background. It is kind of hard to find a quiet place to record in a noisy school, so the best we could do is go into an empty and narrow hallway (that was still close to a noisy classroom). Maybe a microphone or headphones would help... We also could work on better movie editing. (And yes, it was iMovie.)
We didn't have a lot of concepts, but one was mechanical advantage. We figured out the mechanical advantage of bike gears by taking the distance input (the pedal) and the distance output (the wheel) and divided them. The lower the MA the longer the wheel rotates.
I did learn some things, however, like finding the mechanical advantage for a gear on the bike. I also learned about how I should properly ride a bike. I am probably not riding at 90º adjacent to my arms.
Please note: The clips before the mark 0:45 were not recorded by us, but were found online and we thought that they would be good for the intro. The song is not by us as well.
