Vectors

So this weekend's topic is VECTORS. (Think of Despicable Me...) Vector quantities have both magnitude and direction. A vector is represented by any one of the two arrows I am holding in my picture. I used arrows because vectors are graphically represented by arrows: the length of the arrow represents the magnitude of the vector. You connect vectors head to tail, so you add the tail of the second vector to the head of the first vector, like how I do in my photo. The resulting vector (the sum of the two vectors) is called the resultant. The converse is also true: any vector can be broken up into two or more other vectors (applying the ブレクrule, not the フレイタス rule). And as Mr. Freitas taught us via music on Friday, the hypotenuse of a right triangle represents the sum of the two vectors (the opposite side and the adjacent side). Now let's hear him belt out a parody of (I've Had) The Time Of My Life... just kidding...

Kinematics on the Track

This is a picture of me running the 1500m at Punahou for a JV meet this past track season. YAY! (However, I did not come in first. [insert sad face here].) Anyway, this has to do with our lovely kinematics unit because when I run (or as a matter of fact, when ANYONE runs), we use velocity, speed and acceleration! Speed is just a part of velocity, which is a vector, and my velocity during this particular race was 30m/s (JUST JOKING. I wish.) But seriously, velocity is important because that's what makes or breaks your time. You could use the VAT equation (V=Vo+AT) to determine your final velocity based on your initial velocity (normally zero) once you have your time and acceleration. And acceleration is what lets you go past that Punahou pack (except for Elli, who's too much of a speed star) so you can come in 4th or 5th and still look beautiful for your team. So, if you want to go running with me later, join track! :) You'll be a living example of physics in motion AND you'll have nice legs.

Introduction

Hi, Nikki here. I'm a late addition to period 4 and I'm happy to be here. :) I'm also currently in Pre-Calculus so if anyone else is, yay! Maybe we can help each other. As for my other sciences, I took BSCS Biology freshman year and Honors Chemistry sophomore year. I hope to obtain a better understanding of what physics is and how I can apply it to my life; I would really like to have a good understanding of other sciences besides biology.

I'm a junior who likes to be involved in EVERYTHING. I run varsity cross-country and track (1500m and 3000m) and attempt to balance my hectic life with a good dose of reading, songwriting, art, and travel. I like to run run run run run run run run run run run run run run run run run run run run run run run... yeah, if you haven't noticed, I enjoy running.

About this picture: I took this picture on Independence Day this summer. This represents me because I am independent and I felt very at peace with myself when this was taken. I also really like wearing the color red: it's a bold color that makes me feel happy. Another thing about this picture is that I am in my natural element: the great outdoors!

Oh, and one last thing: The title of this blog is a reference to an inside joke I share with Keana... it's kind of about ditzy girls (please don't think that's me, cause it isn't most of the time) but it's also about when I get asked questions (sometimes). See example below.

Person: Um, hi, I'm in (fill in class here)?

Me: ...Yeah?

Person: So, like, I heard you're in (class) too. Can you help me with (fill in the blank here)? 'kay thanks. Bye.

Me: ...Um...
