Physics Period 1= Amazingg

Gossip girl here taking you into the scandolous lives of the mendons physics elite.

Spotted: J getting reprimanded once again for disrupting class with talk about her love R. Come on little J some of us need to pass the midterm.

We started off the class period today with a review game of what we were discussing Tuesday for those of us who forgot it on our day off yesterday. We then discussed and took notes on PE turning into KE. We discussed how one can substitute Vi, a, and d into Vf^2=2gh and that the sum of PE and KE was constant in a drop. We then moved on to discuss the PE and KE of a falling object. We learned that there are two ways to think about it:

• loss of PE=gain of KE
• PE + KE= Constant

Mr. Wirth then demonstrated this principle with a ball bearing loop. We learned that the ball bearing will go roughly to the same height and that energy goes into friction. Next we watched a video called Physics of Fun Loves It! (that was for K Ko) After the very educational video we learned some new fun definitions. We learned that Internal Energy or Q:

• is the amphibs(total for those of you who don't know the lingo) KE & PE of all the individual atoms & molecules
• includes Chemical PE & Nuclear PE
• KE of atoms and molecules=temperature

We learned that the total (amphibs) mechanical energy is the KE and PE of the object due to it's velocity and position. Also total (amphibs) energy is E sub T= KE + PE + Q.

The next topic discussed was the Law of Conservation of Energy which is the total or amphibs of a closed system is constant:

• closed system: no energy is exchanged with surroundings
• no Q acts
• no work is done on or by system

The next topic discussed was the relationship between work and energy:

• work done= the change in PE
• work done on an object= change in total (amphibs) energy of an object

During that class period we also attempted to watch another video but it never loaded, therefore it was saved for another day.

One more thing... BAGEL COUNTDOWN 1 DAY! Lllloves it!

That's all for now, may the force of physics be with you.

You know you love me,

XOXO

First official blog post from a student from period 1...LOVES IT!

I accidentally posted this on my own blog...my bad. So Mr. Wirth asked me to post it on the main class blog.

Okay so I'm an idiot because I wrote this whole long thing and then I pressed preview to see how it looked so far and I COMPLETELY lost my entire post. So here's a blogging tip: DON'T press the preview button so you don't accidentally lose your post. So I have to start all over. Dang.

So how excited is everyone that this is the first official post from a student for our new blog?! LOVES IT! So since I'm the guinea pig of our class, cut me some slack since it's the first post.

Today was a pretty easy day to "pay extra special attention." I gathered some pretty useful information including some sick blogging tips! So when you're next in line for being a super scribe, here's some helpful tips before you blog it up.

1. Always title your posts. Not only does it make it more interesting, it makes the blog more organized. Because I know you all will be rushing back to read my post over and over again, it will be incredibly convenient to find since I have a title on it. LOVES IT!
2. This blog is 5% of your grade, so don't be lazy, put a little effort into it! It's not only an easy grade, it's an easy way for us to learn more about Physics...and each other. That was deep, wasn't it? But seriously guys, I know we're all almost second semester seniors...oops, I forgot about Katie Vaughan. Just kidding Katie, love ya! Hope junior year is going well. I know we barely want to do ANY work anymore, but this isn't too bad. I mean I'm opting to do this first over all of my other homework, so that must mean it's pretty painless.
3. You have 2 days to post after your assigned day of "paying extra special attention" in class. So basically right now I'm being a maj (major, for those of you that don't abbreviate) overachiever and posting the same day that I was assigned to be a scribe. LOVES IT!
4. Come up with a sick signature phrase to become a super scribe. Such as LOVES IT! It gives it your own personal twist. Plus you can make it cute with colors and stuff. Fun right?

So those are all of the blogging tips I have for you today...onto the next topic...the quiz. Oh man.

So there were a few problems that may have been some of the reasons why we didn't do too hot on the quiz

• Units were either M.I.A., wrong, or inconsistent. You don't have to show your units in every single thing in the equation, just make sure you have them correct for your final answer.
• Note From Mr. Wirth - I mispoke regarding units. The Regents Physics rules for ESA (Equation, Substitution, Answer) state that you MUST use units in your INITIAL SUBSTITUTION and in your FINAL ANSWER). Sorry for the confusion.
  
• Points were lost with the math portion for simple errors. Not good. Check over your work a time or 2 to try to catch those errors.
• Incorrect equations were used. The reference tables are there for us to reference to, so we should learn how to use them correctly.
• Read the questions carefully. I know I personally rush through what the question is trying to ask when I get nervous about the quiz, so take your time on this part because it could make or break you in some cases.

A whopping 24 people got an F on this quiz...HATES IT! Only 2 people got an A+ on it. Don't you think it should be the other way around or something? Everyone was pretty shocked...and disgusted at the grades. Do your quiz corrections to help boost your grade a little bit, but more importantly make sure you understand what you did wrong because we will definitely see it again on the midterm. Speaking of...

MIDTERM COUNTDOWN: 17 DAYS!!!

So in order to prep for the midterm correctly we all should:

1. Do our homework.
2. Ask questions (no question is a stupid question...duh.)
3. Seek assistance from Mr. Wirth
4. If you're absent, find out what you missed online or through an amigo.
   

There's another important countdown that I need to make note of...

BAGEL DAY COUNTDOWN: 4 DAYS!!!

And basically the last thing I need to address is our kinetic energy review that we had today...it was pretty lengthy...not. The equation that you need to use is:

KE=1/2mv2

That last 2 is supposed to be a squared but I honestly have no idea how to do that on this thing.

So basically that's all of the blogging I'm doing for tonight. Hope you all enjoyed it and hope I made it fun for you to learn about Physics. Leave as many comments as your little heart desires.

XOXOXOXO (that's for Alex Eberts)

Scribe Post- January 8th- Tuesday

Last week we called potential energy "Stored Energy".
Potential is defined as things that may be possible or might occur

Potential Energy is associated with position.
Gravitational PE- Gravity
Elastic PE- Elastic Force (Springs)
Nuclear PE- Strong or weak Nuclear Force
Chemical PE- Coloumb Force

Energy- ability or capacity to do work

PE- is ready and waiting to do work
PE doesnt have to actually every happen

PE is stored energy

Change of PE = the work required to bring from an initial state to a final state
(No energylost to friction)


Initial (bottom of the Stairs)
Final (tiop of the stairs)

Gravitational PE
Energy of Height
going up is doing work against the gravitational feild

Change in PE= mg(change in h) = weight * Change in height
Change in PE= 20N * (2m)
Change in PE= 40J


Lets discuss the fact that the beautiful RYAN SHECKLER has been officially named the Breakfast Club Mascot. His rock hard body and hot tattoo are part of the beautiful thing that which is breakfast club. We love him and his amazing eyes along with his precious smile. Ryan will forever remain a part of our first period class. <3

Katie has put her first scribe post (an excellent effort by the way) on her personal blog. That's OK, but I'd like it also to be posted on the Class Blog for easier access.
