PHYSICS OF SPORTS VIDEO
For the second project of the first semester, we were given the assignment to create a video on a sport and break that sport down to explain the physics. The goal was to help the athletic program at San Marin improve on that sport. My group decided to explain the physics of hitting a baseball, or, more specifically, hitting a home run. During this project, we learned the important concepts of force, velocity vectors(the horizontal and vertical components of velocity), acceleration, and potential energy. For more on these concepts, see below.

This project was very challenging, especially breaking down the physics. We also had a shorter amount of time to create this project, and it was slightly harder to get acquainted with my group. But after a few days, we got accustomed to each other and the way we worked, and we had an easier time assigning jobs and enjoying each others' company. This was a peak that we had during our project: adjusting to challenges easily. This was something that we did really good on, and I am glad that this project worked out well. Another peak that we experienced in this project was that everyone had a specific job, and the project got completed faster: in other words, we had really good time management. A few problems we experienced were that we kept forgetting to bring our computer for editing(after three days we remembered!), so we know for next time to be better prepared, and to be more organized. Another problem was that we kept arguing during the beginning of our project. We couldn't agree with each other, and we had a hard time communicating. During this time, I gained patience, and expressed my ideas in a calm, formal manner. After each person in our group took a step back, we came back together nicely, and got to finish this project with ease. I also learned the life-affecting aspect of leadership: when we had trouble, I lead the group in another direction, with better ideas and opportunities.
CONCEPTS
-Potential Energy~ this is how much energy an object has prior to it being in motion. It is calculated by multiplying mass, acceleration due to gravity, and height. In this project, we multiplied the mass of the bat(0.53865 kg), 9.8 m/s^2(acceleration due to gravity), and the height of the bat before it was swung(0.8382 m). The potential energy of the bat was 4.425 joules.
-Acceleration~ this is the change of speed in an object. You calculate it by dividing the change in velocity by the change in time. We found our acceleration by dividing 0.51 seconds from 11.43 m/s. The acceleration of the bat turned out to be 22.41 m/s^2.
-Force~ force is defined most often as a push or a pull. It is found with the formula momentum is equal to impulse, or mv=Ft. The force of the bat is 6,525 Newtons.
-Projectile Motion~ there are two components to projectile motion: horizontal velocity and vertical velocity. The horizontal velocity is found by dividing distance over time. The vertical velocity is found by using the acceleration due to gravity and the changes throughout the horizontal arc. Though related, these two components of motion and velocity do not effect each other. Also, when something travels through the air, it mostly has horizontal distance/velocity.
