Today, we turned in our answers to the Kinematics Test Review. We didn't have to turn in the question sheets if we didn't write on them, but we did have to remember to staple the graph descriptions to our review packets.

Then...

We took a test.

And that's it.

I'm not allowed to talk about the test, because the information on it is super-duper top secret, but I'd say that as long as you studied and did the review worksheet, you should probably be fine on the test. There was no homework assigned for tonight.

QOD: Acceleration is measured in units of meters per second squared.  What do those units even mean?

To my understanding, these units of meters per second squared mean that the object in motion speeds up or slows down a certain number of meters per second, per second. That is to say, the number of meters per second squared represents the change in velocity (m/s) per second, a positive number of units showing that the object is speeding up, and a negative number showing that the object is slowing down.

We didn't turn anything in today, but we checked the bookwork from last night, pg 53 #7-10.  She went over #8 on the board since people seemed to struggle with it.  For the rest of the class period we worked individually on our test review.  WE HAVE A TEST TOMORROW. In case you didn't know :) The internet wasn't working, so we couldn't check our answers... speaking of which, I need to go do that now. I had completely forgotten.  Yayyy, physics blog really is helpful! Fun Fact: a muscle in my arms was twitching for the whole class period, it was annoying.  Ask my table about it, it was pretty intense.  The test review is due tomorrow at the beginning of class.
QOD: What do you think will be on the test?
That's easy, there will be physics:)  There will probably be questions regarding interpretting graphs because we did like 27 billion of those on the review assignment and in labs throughout the unit.  There will probably be calculations involving speed, time, and distance and maybe a little ROXY.

Today in class we were given the Kinematics Test Review sheet, which we were shown the key to online by Mrs. Coats- Haan. We were told that the test review will be collected on the day of the test, which is Thursday 9/29, although it was recommended that students should try to do the test review tonight so they can ask Mrs. Coats- Haan questions about it on Wednesday. Next, the class took notes over velocity, including displacement, and average velocity, during which Mrs. Coats- Haan managed to make a few puns about people's names (especially mine). The class also enjoyed a lively debate about what color and pattern to make the rectangle on the velocity notes PowerPoint. Following that we discussed assorted Adam Sandler movies, because of a Happy Gilmore reference on Mrs. Coats- Haan's PowerPoint. After that Mrs. Coats- Haan wrote Hunters name in smiles and mine (Sunny) in rainbow. Also we learned that Physics makes Mrs. Coats- Haan happy. The class was then told to finish the pairs check that we had been given in class a previous day. For the pairs check we used what we learned in class to finish the last three problems. Some specific things we learned in class were how to use ROXY to find displacement. We also learned that average velocity is the displacement vector divided by the corresponding change in time, which will be used on the homework for tonight which is page 53 numbers 7 through 10 in our physics book.

Question of the Day: Why did vectors come up again today?
Answer: Vectors were once again mentioned today because today we discussed displacement and displacement is just the difference in two position vectors. Also, velocity is a vector quantity and average velocity is the displacement vector divided by the change in time.

Want to hear a joke?
A poultry farmer was distressed because his chickens stopped laying eggs. He didn't know what to do about it, but one of his friends, a physicist, offered to help. The physicist came out to the farm, took a bunch of measurements, and went back home to analyze the data. The physicist called the farmer on the phone and said: "Okay, I have a solution for your problem, but it only works with spherical chickens in a vacuum." -Physics joke from The Big Bang Theory
