Physics of Sports
This video teaches the physics behind a baseball pitch. The idea was to improve or teach the skill used in throwing a baseball by knowing how it works and what parts have a really big effect. This video was made in order to help pitchers at our school throw a better pitch by throwing the physics behind it. IN order to do this we made a quick plan or story board and then videoed it. After that we spent the rest of our time editing.

Vectors- You can find the horizontal and vertical components of a vector by using right triangles. If you have the horizontal and vertical components then all you need to do is use the Pythagorean Theorem (a^2 + b^2 = c^2) the horizontal and vertical components are a and b and the original (total) vector is c.
Velocity- The speed of an object in a direction. Our baseball had an average velocity 30.66 m/s.
Acceleration- Acceleration is the change in velocity. Gravity accelerates all falling objects at 9.8 m/s^2.
Projectile Motion- Projectile motion has two components its horizontal velocity and its vertical velocity. Using the Pythagorean Theorem (a^2+b^2=c^2) we can then find the total velocity. The two components of projectile motion do not affect each other. A bullet dropped will hit at the exact same time as a bullet shot horizontally from a gun. Any object thrown at all upward will follow a parabolic arc with max horizontal velocity right before and after it lands and none at the top.
Impulse- Impulse is the power of a collision between objects. It is found by multiplying the force the object exerts by the time of contact. As Tyler threw the ball there was an impulse.
Momentum- Momentum is how much umph an object carries with it. It is calculated by multiplying mass and velocity. The ball had momentum as it traveled through the air
Kinetic Energy- Kinetic Energy is how much energy an object has due to its motion. It is calculated by multiplying 1/2 mass and velocity squared KE=1/2mv^2. The ball has KE during its flight.
Gravitational Potential energy- Potential Energy is the energy stored in an object due to the pull of gravity and its height from the ground. It can be found by multiplying the gravitational constant (9.8m/s^2) by its mass and its height off the ground. By raising your knee as high as you can you build more PE.

We started out looking forward to what we thought was going to be a fairly easy and fun fun project, but it was far from. Initially we had an awesome idea, surfing. We knew it would be a challenge and I was hesitant to take it on, but Kai pushed the idea so we decided to give it a shot. Our first attempt to go surfing never really got off the ground due lack of communication. Our next attempt was a week later and it was all planned but the only two that could go were Kai and his friend, and when Kai didn't get a ride to the beach nothing got done. Kai continued to promise us the videos but in the end we had to switch, and we went with pitching a baseball. Without Kai we got the film we needed in a day and got straight to editing. When Kai came back he decided to step out and just get us the audio, and do voice overs, but when it came down to the wire I decided to do it myself because I didn't feel like Kai would come through.
In this project we definitely could have communicated a lot better, lack of communication was one of the primary reasons we never got out to the beach to surf. We also needed to work more as a team, I feel like for the first part Kai took charge and was really trying to do take charge of everything and do everything, but when he continually didn't follow through I took over and got everything done. I did the most of the editing (Tyler helped a bit), filming, and voiceovers. The only thing that I didn't do was throw the baseball. I felt this was the only way to get the project done in the required time frame. We did however have great ideas that really had potential. We also got a lot done in the five hours that we had to film and produce the video.
