The Physics Journalist Class Objections 1. Mr. Manning did a Notebook Check 2. Work on problems that were homework with a partner 3. Review test on VT and XT graphs taken last week 4. Review problems 2-4 in Acceleratin’ Experiences 5. Do problems 5-9 in that packet 6. Reminder that test is on Thursday and accelerator is due Thursday for extra credit. Homework Do problems 5-9 that you do not finish in class

Today Mr. Manning reviewed the packet that shows us how to figure out velocity, acceleration, displacement, and final velocity. There are three different ways to figure that out, or help to understand the answer: Equations, VT graphs, and Linear motion diagrams.

The Graphs help because a VT graph shows acceleration, and displacement. A linear diagram is a picture that can help you understand the motion and what is happening during that amount of time given. Equations help you to find an answer when you are given some information but not all, you must plug in what you are given then solve for the left side.

You can use different ways to figure out the right answer, there is more than one right way!!

The answers to the homework from the previous night were 2a. 48.9 m 3a. 6.2 m/s^2 B. 18m 4. 765 m 5a. 6.3 m/s^2 B.-14.5 m/s 6a. 71.5 B. 12.9 m 7a. 43.0 m/s B. -9.80 m/s^2 8a. -1m/s B. -2 m/s^2 9a.-2.96 m/s^2 B. 4.7 s

A picture for number 3 for linear motion diagram would look like this:
