Yummy in the Tummy

So today, my sister, my cousin, and i decided to make some DESSERT!!! yum yum. this is the end. but when i was mixing to ingredients i realized that i was applying a force in the perpendicular motion to the mixer, thus applying torque. i noticed that if i held the mixer closer to the middle of the handle, i had more power and control whereas when i moved it towards the top, i had less control of it. this also demonstrates the balancing that we've been working on. as i move farther away from the CM, i lose balance, thus losing control of the mixer. ^.^




addition to previous blog:
ohhh i took a picture of the Lazy Susan when i went to dinner at a Chinese restaurant named Imperial:

Chinese Food

The Chun Girls:

Michelle, Me, San, Kristi, Katie, and Jamie

The picture above is of my girl cousins on the Chun side. When we're not at my popo's house, we go to Chinese restaurants--since we are Chinese. ^.^ Anyways, I was thinking what I could put in this week that pertains to the stuff we are currently learning. Then I was watching the food channel while i was thinking and then i was thinking of pe king duck and all that good stuff and then BAM! it came to me. THOSE LAZY SUSANS (those circular turning tables) AT CHINESE RESTAURANTS! It is a good thing that the food does not fly off when you spin those tables. How is that so? Well the friction of the table and food dishes help. and since you probably dont put that much velocity to the spin, the centripetal force is not that great so the friction ends up overcoming that force, thus the food stays on the table. What if there was a great velocity, do you think the food dishes would fly off the table? Maybe you should try it out...HAHA!

Back to Basics

Okay well i am kinda of sick of collisions and my mind is blank so i decided to do my journal on...

NEWTON'S THIRD LAW...
in...
SWIMMING!

this is my friend, Courtney, swimming 100 breast at some championship a while ago.

in every stroke, as your arms push the water backwards, the water pushes you forward! thus, newton's third law-for every action there is a reaction. in free,back, and fly, the kicking does not exactly follow the same horizontal maneuvers. however, in breaststroke, the "frog" kick follows more of that horizontal action. as you bring your legs from open to close your legs push the water together while the water is pushing on you thus giving you the momentum forward when the kick is finished--your legs are closed.

Silly Me

Okay so this Sunday I went to the senior meet at CORP. and i was drawing while waiting for the pool to open for warm ups. my friend comes a long and plays with my eraser and i spazz out and drop my pencil. when my hand reaches to pick it up as its falling the DULL tip comes in contact with my hand and pushes in when it [the pencil] is compressed between my hand and the ground. i pull it out when its dangling and my friend is freaking out. i was pretty calm although i did get a bit freaked out when i squeezed it and flesh pushed out. but yeah so anyways...i was like hey this is like a sticky collision. haha basically my hand is object one and the pencil is object two and when my hand goes to reach to pencil the pencil ends up staying with my hand--that is until i pull it out. =] so note to self: when a pencil falls let it fall.---although it was kinda by instinct to pick it up thats why so thats why it happened all so fast and BOOM! i get jabbed. haha

No Picture =[

Have you ever hit someone and your hand hurts but the other person seems to be fine?
I am wondering if this has anything to do with the bouncy collisions we learned about this past week. Like so maybe the other person was either hitting really hard or they are way huger than your hand so the energy transferred is bigger thus giving the "ouch" in that instant after contact?
HERE:
m1v1 +m2v2 = m1v1f + m2v2f
so like say you are 1 and the other person is 2
so you have a small positive velocity going forward in the before collision
and person 2 has a high velocity in the negative direction
then after the collision, the person 2 has a small velocity in the positive direction thus you have a large velocity in the negative direction.
thus when the velocity is transfered maybe it hurts the hand.
i dont know.
does anybody think this makes sense? or at least see where im going?
im crazy.
booo.

go raiders ^.^

My Love For...

k first of all.
THANKS LB [LAUREN BABA] FOR REMINDING ME ITS A SELF ASSESSMENT!
k now for my blog:
okay so these are DONUTS. in swimming. where are these you may ask? well they are in the lanelines. in the summer marie, haku, geramiah, and myself restrung 10 LC lanelines. now at first it looked a bit tedious but do-able. however, i was proven wrong. it was a long and arduous task. it took forever and i got many cuts from the frayed wire end. IT SUCKED! and it was fridgen hot. but the music did help mollify the pain from the sun and stringing them. k first of all you have to lay the laneline out. then you have to take them all off and you can't just take the wire off you have to start off with a reasonable length and push it off the end. easy rite? NO! its not. wen u start to get to the end you have to walk all the way to the end and walk it outtt. hah. but then u have to keep doing that til all of them are off. then you have to organize! cuz it helps in the long run. and there are 3 different pieces, times two because white and red colors, equals six large piles. OMG! and then you have to get rid of the junk cracked ones. so there obviously is a pattern and i wont even get to that. but it takes very long to do it! my back was so sore after that. it took some days. >< style="color: rgb(204, 51, 204);">fun in a way. i got to hang with my hommies ^.^ and i got paid. haha. and also it was for something i love to do---swimming. i have more respect for lanelines now. and DON'T PUT YOUR WEIGHT ON IT! or i shall kill you! haha. if u break it, O.o beware! heh. well anyways...what does this have to do with me and physics?
well...thats exactly how i feel. its very tiresome on the brain like chapter 5&6. but i love the labs and the atmosphere. i love our physics class! it is one of my favorite classes which is a surprise cause science in the past hasn't really been looked forward to. i LOVE physics!
-steph outtt

inertia overcomes mind

this would be my crazy "family" at LC States '07 ^.^

Okay so AFTER class day, we had a senior meet at CORP. twas very windy and cold. anyways so i was swimming 200 back and well i take out the first 50 with the momentum i get from my dive. so its supposedly the fastest 50 of the 200 . then i usually balance out in the 2nd 50 and sometimes when i get lazy, i rest the 3rd 50 and "save" my energy for the 4th 50. okay well this is very bad thing to do and my disappointed coach would say,

"that was stupid because it takes more energy to get back to the speed you were at."

now i realize that is true and it isnt smart to THINK that you can save your energy for later. this has to do with inertia because it takes more FORCE as we learned in chapters 5&6 to change speeds. silly me, now that is what i think when i want to give up and just try at the end---SANDBAGGER. >.< BUT this time i had a reason because i was super tired already then we had class day then the meet. so i was very sick to the stomach and tired. haha. good thing i skipped morning practice that day! haha. anyways...was my coach wrong in using the term energy?

slightly embarassing

the lee side cousins with popo

okay so first of all i dont have a picture of the subject of my journal but this was the same night, i think. well i know that this picture was taken at Hy's and my experience happened at Hy's with the same people. so yeah. alright and if i did have a picture of it, it would be purely luck and i dont know if i would have want to put it on anyways. haha. okay so basically when i was going down the stairs, i ate it. my sandals were new and i forgot to scratch the bottom of my sandals. so basically there was no FRICTION! the usual gravity and normal force canceled each other out, but as i was walking down the stairs there was nothing canceling out that force (which would normally be friction), thus my acceleration from going step-step, to FALL! haha so all you who buy new footwear with a smooth bottom, SCRATCH them up! or you will pay! haha

Different Initial Velocities

This is a picture of me and my friends jumping from bed to bed at the Hilton. What does physics have to do with any of this? Well, as you can see we all are in different positions vertically and horizontally, yet we left our positions at the same time. [Oh, by the way, the two pink shirts are going one way and the white one is going the other, if you did not get that] Anyways, this is due to the vertical velocity that differs in all of us. My friend who has completely landed had the lowest vertical velocity, making her time in the air the least. Next was me [in the pink shirt and pants]. I guess you could say that I am in the position of the end of the parabolic path that a projectile takes. Then there is my other friend who is still completely in the air, having the highest vertical velocity, resulting in the longest time in the air. I like this picture because it shows the effects of different velocities and because it reminds me how tiring, but fun it was jumping all around. ^.^

People Hunt

WATER BALLOON FIGHTS ARE THE BEST! I was thinking of what to write for this week's journal. Being relevant to what we are learning, I thought of the projectiles in life and of pictures that I have. Then I remember having a water balloon fight and how the aiming technique is sort of like the MONKEY HUNT lab we did. Well even if it is not exactly like it, when the water balloon is thrown, it is a projectile. It's the same as the video we had to "cut" up and observe their graphs. The Y position graph takes the shape of an upside down parabola and its velocity graph is a negative linear graph. The X position graph is a positive linear graph and its velocity graph is almost a a straight horizontal line, having a slope of zero. However, it does not because of the effects of air resistance. So next time you are having a water balloon fight, throw it differently and think of how its 4 graphs would look like and have fun ^.^

So Far in Physics...

This is how I feel about physics.
*NB: you should let this load b/c when it goes all at once it looks cooler.

Physics is fun but at the same time challenging. The material is pretty easy to grasp especially after we do the labs that embrace the concepts we are learning. At first it was kind of blurry to me but then after a while I seemed to get the hang of it. I never had such a class involved with the computer and technology so it's kind of exciting because I love going on the computer and taking pictures. I seemed to be doing pretty good, that is, until the test. I am kind of bummed about my grade and what it brought my average down to, but I am hoping that I can bring up my average before the quarter ends. I am worried that I am going to become one of those that do well all the way up to the test and bomb the test. It's kind of like what we call a "practice swimmer" in swimming. Practice swimmers are those who dominate in practice but their performance in meets don't seem to match the swimmer they are in practice. This course so far is way better than I expected. It's actually kind of fun. I didn't really have a clear vision of what I thought it would be like but this is by far more hands on than I thought. I hope that it only gets better in the future.

The Thrills

The first picture is from this summer at the waterpark on cliffhanger. The second one was of my friend jumping off of the Waimea rock at Waimea Bay after the Cholo's ocean swim.

When we started to talk about free fall and acceleration I thought, "Wow I wonder what it would be like to be that ball that we always talk about." Later I realized that I have experienced free falling. Even though there is water and a slide on the cliffhanger, when you actually come down it, your butt is actually not touching the slide, well for me it wasn't, at least not until you get to the bottom where you get a bad wedgie =P. Also, in the cliffhanger there is water to help give you this free fall experience since the slide is not exactly vertical. Still, in the cliffhanger, you do experience some sort of free fall. As for the Waimea rock one, you do experience free fall. You are falling straight down and there is nothing to guide an angle to fall. These two things give us instant thrills and make fun experiences which is ironic because some people say that they wish they could fly but stupid gravity is stopping them. Yet, gravity does have its way in the fun department of life ^.^

Sickness Graphs

Sickness Remedies: Jell-O, Tylenol, Li Hing Watermelons, and Water

On Tuesday, August 28th, 2007, my friends and I were in the pool office waiting for my friend, Marissa, to come so we could start our workout as a group, embracing the "One Team" spirit, although she goes to Punahou =P. One of my friends, Jodie, had some Sprite. Now I hadn't had any liquids since lunch and being a swimmer, my norm is being surrounded by liquid. So I ask her for some and she replies, "Yah yah go, but I'm sick." Thinking that I never get sick and therefore I'm invincible, I say, "Ah whatever," and take a sip...and another...and another. So I go home that night, and all of a sudden my throat starts to hurt. Well as the night progresses, so does the pain and the fever I soon developed after the throat pain. I end up falling asleep on my Precalc homework. I wake up the next day and being an 'Iolani student, there is much to do everyday, and missing one day could kill you. So I went to school, but as the day progressed, I felt like i could hardly stand. Good thing we got period 6 free that day, because after lunch I felt like jell-o. So I went home right after school that day and slept, accomplishing no homework. The next day I just slide by and feel like I'm getting better. Thursday is looking up. Maybe Friday is going to be good. Unfortunately, Friday was one of life's little surprises. Oh, and the surprise just got better on Saturday. Let's just put it this way, I went to sleep at 6:30pm on Friday and woke up at 12pm on Saturday afternoon. Also, my fever grew to a 100.3 and I have a low normal temperature. Anyways, I went to sleep and on Sunday, today, I feel a lot better. I finally feel I'm just a corner away from being completely better, hopefully. Anyways, I can hardly think right now and my sickness journey just makes me think of what a sickness graph would look like, since we're studying graphs and all.

So I made a "Energy-placement" graph:

and a "Energ-ocity" graph:

Now I challenge you to make an "Energeration"graph! Have fun and enjoy whats left of the three day weekend! -Steph out.
