Rotational Motion Introduction

Today we began our rotational motion unit with an introduction of angular quantities and how they relate to linear quantities.

Notes: Rotational Motion

Homework: Chapter 7 (p.227) #1, 2, 5, 10, 14 and Rotational Motion TIPERs #1 (email miss.volkening@gmail.com if you need a copy).

Energy Test

Today was your energy test! You have no homework, so please enjoy your three day weekend.

Vector Quiz + Keep Studying

Today we took a very short quiz on vecotr addition. We will be having these every few weeks for a while, each slightly more difficult than the last. This first one will get you one extra credit point for the correct answer and another extra credit point for correctly scoring a peer's paper.

The rest of the period was yours to prepare for your energy test, which is tomorrow. You can find the practice test, solutions videos, and abridged answer key on yesterday's blog entry.

Energy Practice Test

Today and some of Wednesday are yours to prepare for your energy test on Thursday. On Wednesday we will have a short (one question) quiz on vector addition.

Energy Practice Test

Here are some solutions videos from a couple of years ago(may not perfectly match energy practice test).

Multiple Choice #2
Problem #1
Problem #2
Problem #3

Below are the abridged answers.

Practice Time!

Today we spent the first part of the period going over one of the homework problems, then spent the rest of the time working on, then peer grading, Energy TIPERs #7 (email miss.volkening@gmail.com for a copy). We did not turn it in, though.

I actually did not assign homework, but if you do have a test coming up next Thursdy, so if you want to start looking at the practice here it is: Energy Practice Test.

Also remember that my tutoring next week is on Monday instead of Tuesday.

Using Elastic Potential Energy in Energy Conservation Problems

Today we basically did several examples of energy problems that include springs:

Homework tonight:

Energy TIPERs #6
+ p.160 #35, 39, 67. We will do one in class together tomorrow.

Elastic Potential Energy

Today we defined elastic potential energy.

Notes: Elastic Potential Energy

Homework: p. 159 Problem #20 + p.157 Conceptual #11. Also start the front of Energy TIPERs #6 and we'll do the back tomorrow.
