Evaluation

So I currently feel a little lost in physics, but not as badly as I was in chemistry. chemistry was much worse. physics is also more interesting than chem. but anyway, I feel like Alice in Wonderland because she gets lost and she wants to find her way back to the normal world.

I have put effort into this course, but I might have been able to put more into it. or maybe not. I think that I might have killed myself in my other subjects if I had tried even harder in this class. It's a feeling sort of like Alice because she tries to find her way back home, but she gets sidetracked really easily if I remember correctly. Does that have any relation to my situation? Hmmm...

I hope I can get better grades next quarter, but I'll be happy just as long as I get grades above B-. yep. I hope that friction quiz didn't strangle my grade to death because that would be bad.

By the way, everyone should read Through the Looking Glass by Lewis Carroll because its a really great story!

More Physics in Football!

Last night was the football game against St. Louis and Iolani won!!! It was 35 to 30 :D It got really intense at the end with the drums...and everyone was yelling "Go Defense!" yep. Anyway, projectiles.

When the person does the kick off for the other team and the band plays "Back in Black", the ball flies in a projectile motion. In a projectile, there are two motions, a horizontal and a vertical motion. The horizontal velocity stays constant throughout because gravity has no effect on it. On the other hand, the vertical velocity decreases at a rate of -9.8 m/s. At the very peak of the ball's motion, the vertical velocity is zero while the horizontal velocity stays the same. As it flies back to the ground, the vertical velocity increases negatively at a rate of -9.8 m/s.

The vertical displacement would be zero if the ball is kicked off the ground and the other team does not catch the ball. However, if the other team does catch the ball, the vertical displacement is the height of the ball when it is caught. The horizontal displacement is the distance it traveled from where it was kicked to where it was caught.

Yep, the game was super exciting at the end! And all the Raiders looked super happy. Today I talked to a friend on the other team and he said he considered quitting football that night. St. Louis must've been very sad.

The Orange Car

I do not actually have an orange car, but I wanted the car to stand out in the picture.

So, I was explaining to my mom what this project is about while we were in the car. I decided to use the car as an example just as we were turning the corner. The car is an example of physics because my mom decelerated as we neared the traffic light. Then as we turned the corner to the right, the velocity changed because we were going in a different direction even if we were driving at a constant rate. The velocity involves both speed and direction. After we turned the corner, my mom accelerated in order to change lanes. Then as we went up a hill, she pressed on the gas peddle to keep the car at a constant speed.

Physics at Football Game

For pep band, I attended the football game for Iolani and Damien. We were playing "Hot Hot Hot." Then as soon as we stopped playing, we heard a lot of yelling. One of the Iolani players was zipping down the field and no one could stop him, so Iolani got a touchdown =D Anyway, there was physics in that!

His displacement was about 35 yards (I don't know the exact amount because I didn't get to see the entire play). Displacement is the direction and distance of the shortest path between an initial and final position, so even if he traveled more than 35 yds while trying to get around other players, his displacement is a straight path. He must have accelerated because after he got out of the crowd of the other players, he could increase his velocity with less people blocking him. He had to decelerate and come close to a stop because one Damien player almost got him. Once he got around that other guy, he accelerated again. It was very exciting, yup.

I drew the picture because I don't have a camera to connect to the computer. The people in white are the Iolani players. The purple people are the Damien players. The guy in the very front is supposed to be holding the football, but it's hard to see.
