Practicing Spring Problems

First we went over your choice of last night's homework problems. Most classes chose #39, so I got a photo of it:

You then started working on Energy TIPERs #6 which we will peer grade/edit on your modular day next week. Email miss.volkening@gmail.com for a copy.

Elastic Potential Energy

Today we added another form of mechanical energy: elastic potential energy. This is just another place for energy to go.

Notes: Elastic Potential Energy

We completed Energy TIPERs #5 in class; email miss.volkening@gmail.com for a copy.

Homework is Ch.5 (p. 160) Problems #35, 39, 67. We will do one of these together in class tomorrow - you vote on which one, so at least try them all!

Lab: Energy of a Bouncing Ball

Today you completed the lab Energy of a Bouncing Ball. There is no homework tonight because we want you to be rested for the PSAT on Wednesday.

Work and Energy Practice

Next week you are doing a lab, so today you picked up the lab instructions: Energy of a Bouncing Ball.

We also went over how to solve an energy problem that includes work, then practiced on some problems. Whatever you didn't finish in class is homework:

Energy TIPERs #4 (email miss.volkening@gmail.com for a copy)
+ p. 161 #45, 47, 89

Here is the problem solved with numbers:

And again without numbers first:

Work

What is work? This is not a philosophical question.

Notes: Work

We worked on Energy TIPERs #3 in class today, which you kept as notes.

Homework is p. 158 #8, 9, 13, 16

Energy Problems Practice

First we went over #37 from yesterday's homework:

We spent the rest of the period practicing more problems. If you didn't finish in class, these are homework:


Energy Conservation Practice (email miss.volkening@gmail.com for a copy)
p. 160 #32 & 38

Mechanical Energy and Energy Conservation

First thing today, you got new seating charts. Meet your lab partners for the rest of the semester! maybe exchange contact info.

Next we started talking about mechanical energy and its conservation:

Notes (remember to run as a slide show!)

This left about 10-15 minutes left in the period, but hopefully you used it to start your homework:

Energy TIPERs #1 (email miss.volkening@gmail.com for a copy)
Energy TIPERs #2 (email miss.volkening@gmail.com for a copy)
Ch.5 (p.160) Problems #25, 33, 37

Test!

Is it test day! Good luck and have a great fall break! Don't forget you have three FRQs to try in between sleep catch-up and Netflix.

Here are some other things you can do over break:

More Work Time

We are still reviewing for the forces test on Thursday. See Monday's blog post for details.

Forces Practice

Today I checked your labs from Friday, I gave you missing assignment reports, and you received your practice test. Below are some videos I made last year on how to do the free response problems, but beware: the numbers of the problems are different and I may grade differently.

Solutions Videos
#1
#2
#3
#4

Below is a picture of #1 and #2 done with steps color-coded by Gabby Vindiola:

Your test is Thursday. I understand that you have tests and presentations in probably every class this week, so we'll have unstructured work time all week. On Thursday you will get some old AP FRQ to try over fall break.

Lab: Finding the Coefficient of Static Friction

Today was slated to be your coefficient of static friction lab, but it seems a lot of you are experiencing an acute time crunch. Therefore, what I am going to say is that your lab is due on Monday but you can either do it in class or at home.

Lab: Finding Coefficent of Static Friction

• Must complete pre-lab first (#70 in chapter 4 may help)
• Complete lab in your lab notebook only. Due Monday.
• Lab itself ca be done at home easily

Next Week

• Test on Thursday
• Practice rest of week - no new material

Friction + Inclined Planes

We've done inclined planes problems. We've done friction problems. Time to combine inclined planes and friction!

Today we worked on:
Forces TIPERs #4
Friction TIPERs #4
p.117 #30 & 51

Your homework tonight is to finish any of the above that you did not finish in class, PLUS do the pre-lab for our lab for tomorrow. Email miss.volkening@gmail.com for copies of the worksheets.

Below is a problem we did in class together.
