Review of the year

TO review this year will take more than i can possibly write, we have learned and been through too much to just write a blog about it. Through out this year, there were many concepts we learned, and many skills we obtained to not only become physics experts but a better student in all aspects. Theres no real way to explain the skills we learned, but i will admit that at first, i really didnt understand the skills Mr. Abud was trying to teach us, but now that its been a full 180 days of his class, and ive reached the end, i now really appreciate the skills i have taken away from his class, and i hope my class mates did too. Ive changed some aspects of my work habits (its really hard to change anything about me, so i give Mr. Abud some props. Ive become more interested in the lessons i can learn, rather than the grade i get. I can learn a lot from all my classes, but they keep us worried about our "grade", not the knowledge we take home after the class, which now leads me to get a better grade, but I still don't know much about the subject. In this class, my "grade" never matter, I just paid attention every day, got involved, and learned a lot about physics. That's suppose to be the point of school anyways, right? Everything from way energy is transferred, to the gravitational pull of the moon, I felt confident about. Each and every day I would enter that class, although I may not seems super focused, I was learning something new. Being in here for 180 days, I have to say there isn't a single thing that I would change about how the class is run. Well, there is one thing. There should be a super big picture of a mantis shrimp on the board, that'd freak everybody out, and you would get a good kick out of it. Besides that, if that class continues to run they way it ran for me, these next coming generations of students will have a much different, better perspective of learning, and that's the biggest lesson I learned from this class, perspective. Thanks for a great year Mr.Abud, hopefully I will see you over the summer and you can explain to why it's (in physics terms) unsafe to drive with no doors on my jeep or something, have a great summer!

Week 22

This week my group and I have been working on our cardboard boat. We've started so far by a simple 8 foot box in which we have cut, taped, and shaped into a (hopefully) workable boat. We're trying to make it as big as possible, due to our fear of us just getting into the boat and sinking it if its too small. We have been using the skills we learned from the aluminum foil experiment that we conducted in class to find out how much surface area we needed for our weight. With 8 feet of boat, we have enough surface area. What I learned from the testes we did in class was that a certain amount of surface area carried only a certain amount of weight, so we were better better off with the larger boat than trying to risk making a smaller one. At this point, the boat is still in its less developed stage. It's ready to row, sure, but it has no form of decorations and no form of any hydrodynamic setup, so this week need we are going to have to work on it and really get it to where it is presentable. I believe Daniel and I are going to be the rowers, or it may Mary, but we will see. Something I learned for sure is it was kind of easy to find the water line on the boat. Judging by the surface area and the amount of weight being used on the boat (rowers), I can't imagine it to be too difficult to find out where to put the line of tape to judge the water line. Overall, building this boat has been a fun job and I'm excited for the races!

Week 24

This week, things got very complicated very fast. But no need to fear, Mr. Abud was there. We began learning about Energy, power and work. It was a pretty easy concept to grasp. They all use and need one another to perform their function, but what got me nervous and confused was memerizing and using the formulas to figure out the work and power of certain scenerios given to us. It was very easy for me to confuse the energy formula with the watts formula with the work formula and so on. After out experiment of us running up and down the stairs, it began to make more sense to me, but again, the formulas were still throwing me off. I regrettably didnt go to Mr. Abud for immediate help, as i was struggling with the concepts we learned. Fortunitly though, i managed to get a good nights sleep on Wednesday night and had a good cup of Caribeu Coffee in the morning and on Thursday, i really had a light bulb come on for me. I wont lie, i didnt suddenly become a genius with this stuff, but i think i did much better on the assesment than i would of if i didnt manage to understand the concepts the way i did the day before. The assesment was a little tricky,i was struggling with the last 4 problems due to me mixing up and mistakenly using the wrong formulas for some of the questions, which caused my table to yell at me for taking so long to finish my assesment so they can talk, but atleast i (think) figured it out in the end and hopefully my heavy attention-paying on Thursday paid off. I dont usually get hung up on the concepts in this class, but when it comes to multiple formulas that must be used correctly and with one another, i really was strained. Over all, i found this week very helpful. I learned alot about how energy, power, and work relate and how i can calculate the amount of horse power i have and other objects have during a given time. This information helps alot, and im glad i managed to understand and use it.

Week 23

This week we did the boat races and I must say it was pretty intense. I learned a lot about how the way we structured our boats reflected the way we perform. For instance, our boat was very long and wide so it had no tipping or sinking problems but we weren't as quick as some people with smaller boats but sunk soon after in most cases. I like the way the regada is setup so there isn't anything I would change. For the questions, here's the answers: 1: I believe the sinking of the boats that I saw had to due with weight distribution. As people were entering the boat, they will not equally distribute their weight, causing the already flimsy boat to cave in due to in balanced weights. The second factor for the sinking was surface area of the boat. Typically, the boats that sank had very little surface area so as eight was added, the boat was not able to push of the water to remain of about the water line, causing it to sink in. The third factor was the material. Although we all used cardboard, some people decided to use thinner cardboard with more cuts and pieces than some other boats like our, where we used high strength cardboard to resist the water. 2. All the boats that didn't sink had one thing in common: large surface area. It may not necessarily be "large" surface area, just large enough to support the weight of the rowers to keep them afloat. The physics behind it is that the larger the surface area, the higher of the water you will remain due to more parts of the boat pushing off the water. 3.this would be important to a captain because if all the mass is lower in the boat, it makes the boat more stable, so if the captain were to sit as low as possible as well as his fellow rower during the race, they would much more stable, as opposed to if one of them stood up and caused most of the weight to remain higher off the boat, causing it to be in stable. 4. Our boat was based off of having the most surface area as possible. Our success was being able to keep the boat very stable through out the race, although our failures was the over all size. It was too big to move at a fast speed so although we made 2 laps of successful rowing, we would never come in first place. We also had the success of the best looking boat, which earned us the swag award. 5. Since I was 10 I have been rowing kayaks up north many days of the summer, so I had the technique down pretty early. The best way was to curve the paddle into the water so the he hole bottom portion of the paddle was under water, and then push off with a slight twist. This gave me power and constant high speed through out my kayaking and cardboard boat runs. In physics terminology, the deeper the paddle, the more surface area I can push off of causing more power to be brought against the boat to keep it moving. 6.I would make the boat a little less wide, shorter, and make the front end a little more sturdier and more hydrodynamic. Thats the only issue we had.

Week 21

So this week, we took what we learned about centripical force the week before and applied it to astronomy. Our own Earth is in centripetal motion as we speak, always being pulled in by the sun, But the earth keeps trying to go straight. Thats why people mention the worries of the Earth losing its orbit around the sun, because the earth will just start going straight into some dark area of space. We also learned that the moon doesn't really orbit the earth... WHAT? Thats right, it doesn't. It goes around one side of the earth, and just goes right back again. Something we didn't mention, but I thought was important that I learned awhile ago is that since all objects have gravitational force, the moon does pull on the earth, which is the reason the ocean has low and high tide. The moon pulls the water on the earth, causing it all to move towards the middle of The ocean, away from the beaches, and then back again. We learned all about how the earth is on an axis, and that it is actually warmer on the earth when were farther from the sun, because the angle it is pointed towards. Over all this week was good for me and it was really interesting.

Week 20 (was not in class)

Week 19

This week we reviewed and learned more information on centripical force. We revised alot of the things we learned the week before. A very helpful test we did of centripetal force was when a fellow class mate was walking in the middle of the class, and the teacher kept pushing her away from the line she was walking on, just like how a person in a car will be pushed to the side of his car when he's turning. By this week, I understood all the standards and the only thing im having trouble learning how to measure the distance using the formula on the assesment, but I got over it. The physics behind centripical is really to understand, so it was fun learning it. It was also interesting learning it because I take the doors off on my jeep in the summer, and its nice to know what direction im going to fly out of my jeep when I turn. Another standard we learned was the different force needed to keep the object in motion while in centripical motion. Thats why when your in a car going around a track, being in tightest part of track would end up pulling the most G's, as oppossed to being on the outside of the track, where the least amount of force is being pushed on you. Some of the questions on the assesment did throw me off, I didn't read them correctly at first, like "what way did the PASSENGER go when the vehicle turned right" I just didn't read it correctly. Over all I liked this subject, and hopefully the next subject we learn will be similar.
