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
