so i jus put this picture up for fun...haha
and cuz i didn't have any other pictures to put up...but i shall explain some static electricity stuff that happens in my everyday life.. so everyone know that on the weekend iolani student are supposed to do homework and stuff,,, but i dont' really like to do that..most of the time. so normally my parents go out and do errands and stuff and they say, "gavin, be productive and study." and i say, "okay see ya" once they leave i do all sorts of stuff. play games, watch tv, watch movies, lift, and so on..but i noticed that whenever i watched tv there would be static electricity on the screen i think. so when i was younger and didn't know better my mom could come home and feel the tv and be like, " hey you were watching tv! grrr!" but i've learned since that and now i wipe the tv screen before my parents come home. i'm guessing what happens is that some how the tv screen is charged and when i wipe it down i ground it so that no more static electricity is left on the screen...of course i don't do it now because my mom really doesn't care. and most weekends i'm out of the house most of the time. so yeah. there is also static electricity when i comb my hair sometimes.

one weekend..a long time ago i think..erika took this picture of me doing a lame front flipthis was located at china walls.. it was the only picture i could find already on my computer and couldn't get anymore because i don't have a camera at the momment but yeah...theres some torque in this picture. so when i ran and jumped my foot applied a force on the ledge of the wall causing my boday to rotate in the air. the center of rotation is probably near my belly button or yeah some where around there...the lever arm is from the force to the point of rotation so from my foot to my belly button about...yup with enough torque and force in my jump i was able to complete a flip...when i got into the air i tucked my legs kind of...i'm not sure what physics terms it is but because i tucked my feet in closer to the center of rotation i began to rotate faster and fully get over and complete the flip..i think i might have over rotated and landed on my face this one!! haha
ouchi...lol thats like courtny's last name! haha w/e

kay...so this evening my dad and me decided to do my physics journal...lol
so we decided that we should do a belly bump (or should i say Ab collision). so first to make it interesting we weighed ourselves on my scale. you may not be able to see it that well but my dad weighs 143 pounds and i weigh 131.6 pounds. then we lined up, my mom focused the camera and we jumped into the air thrusting our bellies(abs) into each other. it was a success!! and it was supper funny!! but i saw that my dad moved backwards as i moved forward. this is related to physics b/c of momentum and impulse. our momentums were obviously different
b/c my dad went back as i went forward but our impulses were the same...even tho i had a smaller mass than my dad, my velocity was greater causing me to have a bigger momentum. P= m x V thats why
if i had a bigger velocity but a small mass i was able to counter act my dads bigger mass and smaller velocity. THIS LAB WAS FUNNY...

This summer my friends and I went to maunawili falls in Kailua. This is a natural water fall where you can jump off into a pretty deep pond. First we had to hike into the trail and finally we found it by following the stream up the mountain. It was tons of fun. Okay so when you get there you can jump off from different heights ranging from 40 to 10 feet. I went to the top one. When i was standing on the rocks i had all potential energy and no kinetic energy. Once my foot left the cliff and i jumped out toward the pond i began to lose potential energy and gain kinetic energy. there was no energy lost but it was being transfered from potential to kinetic energy. The equation for kinetic energy is KE=1/2mv^2 and the equation for potential energy is PE=mgh.

Physics so FAR!!


This is a picture from last year during wrestling season at the ILH jv championship. This picture is related to physics because physics has so far been my hardest class this year and i think wrestling is the hardest sport i have ever done. But although it is hard i don't mind the challenge of physics. It is very interesting to me and i don't mind putting in the extra effort to do well. In physics so far, i haven't done that well on quizes and tests which i have to work on. i see those as just obstacles that i have to over come. last year in wrestling i weighed in at the 119 weight class but had to bump up two weight classes to wrestle at the 130 weight class the day of the championships. i ended up trying my best and winning. that's what i plan to do for physics this year, to try my best and do the very best job that i can. like wrestling physics is very hard but also fun for me. i enjoy participating in class discussions and working on labs in class. i find if fun because in all my other classes we just lecture and take notes. in physics you actually get to learn the material and see it happen in real life experiences(the labs). also the journals have helped me broaden my view and see physics in my everyday life activities which is way cool.

My anxieties and reservations are probably my laziness and bad time management. I think i need to put more effort into my work and not leave things to the last minute. Although in physics i normally do my homework right after school in a study group so my friends and i can help each other if we don't know whats going on. It helps me get a better understanding sometimes. After school now days I'm really tired and sometimes too lazy to finish homework and i just put it off to the next day (which is bad). Other than my laziness and not having enough time, i think physics is a manageable class and if i just put my mind to it i can do well.

My goal for physics this year, is to understand and learn the concepts that are taught in the class. I also want to get my grade up if that is a possibility that would be great. Another one of my goals would be to put more effort into physics, that would ensure better working habits and hopefully help my quiz and test averages to gradually increase.

If i work hard in physics like i worked hard last year in wrestling I'm sure anything is possible. I'm looking forward to a super fun, challenge overcoming, concept learning, awesome year of physics!!

Newton's First Law

This weekend i totally forgot about my physics journal. there was just so much going on. Like on saturday i went to the game and it was EPIC!! we beat st. louis!! the game was pretty intense and came down to the wire but we pulled through and it was mean! sunday i worked on my collage for senior page which was fun, but took a long time. so i was browsing through my pictures and i found this one. this picture is a good example of Newton's first law. if an object is at rest or at a constant velocity it's net force is zero. in this picture trevor and i are sitting on the top of a flag pole thing on the top of the koko head trail/hike. the combined force of our two weights on the pole is about 126+140=266 pounds. which means the pole is pushing us back up with an upward force of 266 pounds. this would mean that we are at equilibrium.
