This week's unit was all about kinematics, the study of motion. All around us, there is some kind of movement taking place--a car speeding past, a leaf falling from the tree outside, or a person (whom we'll call Kekela) jogging, as depicted in these pictures.Distance is the total path length of something. The distance of Kekela's running path is about 5 meters, 2.5 meters from her starting point to the door and 2.5 meters running back. The term displacement describes how far something goes in relation to its starting point. Therefore, Kekela's displacement would be 0 meters because she ended up at her initial position.
So I was sitting in my dorm room wondering what picture I could use to relate to physics. Mr. Blake said to just look around, so I glanced out my window and saw the same view I've seen everyday since school started. After I thought about it though, I realized something outside that was really simple and related to our lesson, which had to deal with units and relationships. I figured that as the wind speed increases, so does the movement of the trees outside. This means that they are directly proportional to one another. Similarly, as the wind speed decreases, the movement of the trees decreases as well. This picture depicts the trees blowing in the wind.
Hey, my name's Shelly Preza. I've been a boarder at Kamehameha since 7th grade, and I come from the island of Lanai. When I'm home, I really like to go to the beach, go hiking, or quading. Freshmen year, I took biology and thought it made a lot of sense in relation to real life. Last year I had chemistry with Ms. Higa, which was...interesting. Although I didn't totally enjoy every aspect of the classes, I did alright with both of them. Currently, I'm in Honors Pre Calculus. This year I hope to learn to be more interested in science and learn things that can apply to things I see everyday. On another note, hula is something that really defines me as a person. I've been dancing for about eight years now, and I've travelled a lot because of hula, including to Japan and Kauai. For the past two years, I've been lucky enough to participate in Ho'ike. Needless to say, hula is a major part of my life.
