Honors: Forces Study Guide

Today is your day to work on the study guide for our second test. We also counted stamps today. Next class you will have about 45 minutes to last minute studying, and the last hour will be your test.

Period 4, I have to proctor AIMS on Wednesday, so make sure you email me any questions Tuesday as you will not see me Wednesday. miss.volkening@gmail.com

Here is your study guide for your second test: Forces Study Guide. Your test is Friday.

Honors: Finding g With Centripetal Force

Today we used centripetal force to verify the acceleration of gravity near Earth's surface. The bellwork is below. Here is the lab.

Honors: Centripetal Force

Today we talked about centripetal force and practiced a problem combining circular motion and friction. Your homework is Circular Motion II.

Today we talked about centripetal force and practiced a problem combining circular motion and friction. Your homework is Circular Motion II.

Honors: Rotational/Circular Motion

Bellwork became a sort of notes today:

We went outside to run around in circles to discover the relationship between tangential velocity and radius and tangential velocity and rotational speed.

Homework tonight is Circular Motion I.

Conceptual: Centripetal Force Lab

Today we completed the Centripetal force lab - it is homework if you didn't finish in class. Bellwork set it up:

Homework tonight is Circular Motion I.

Honors: Momentum/Rotational Motion/Gravity Study Guide

I was going to try to squeeze in a lab before the next unit...but then almost no one turned in Momentum III and those that did left most of it blank. I also found out that I'll be gone on Friday and I didn't want you doing a lab while I'm gone. So today (and tomorrow and Friday) are going to be work days. In addition to completing Momentum III like you were supposed to, you can work on the study guide for our second test, which will be Monday.

Study Guide

Honors: Orbits

Today we talked about why astronauts seem to be floating when in orbit even though they are not "weightless." We also derived an equation for the mass of a body that is being orbited.

Honors: Centrifugal Force

Today we briefly talked about centrifugal force, which is a pseudoforce (fake force) but is still pretty cool. Centrifugal force appears if you have a rotating reference frame and is indistinguishable from gravity to a person inside that rotating reference frame. We watched a couple of clips from 2001: A Space Odyssey that show how a rotating reference frame could be used to create "artificial gravity."

Here are the abridged answers for the study guide posted yesterday. We also counted stamps.

Conceptual: Microgravity and Unit 8 Study Guide

Today we very briefly talked about why astronauts orbiting earth seem to be "weightless" but are not. The rest of the time was used to start on your study guide (I'll post the answers tomorrow). We'll be counting stamps tomorrow and your test is on Friday.

Honors: Centripetal Force

Today we talked about centripetal force and practiced a problem combining circular motion and friction. Your homework is Circular Motion II.

Honors: Rotational Motion

Today we introduced the two kinds of rotational motion as well as the two kinds of speed/velocity involved. We did run around outside for a bit, but there are also notes below. Your homework is Circular Motion I.

Conceptual: Centrifugal Force

Today we talked briefly about the pseudo force centrifugal force. This will not be on the test - I just wanted to show you some practical uses and tricks involved.

Unit 8 Study Guide

Today is your one and only work day to get ready for your Unit 8 Test. Your study guides are below. You also need to count and record your bellwork stamps.

Aaaaaand here's an extra credit assignment, open to everyone:

Extra Credit: Universal Gravitation II

Test Tomorrow!

Orbits and Microgravity

Due to the unusually cold weather, Desert View started late this morning. Therefore periods are only 35 minutes each, so I am postponing our discussion of tides and black holes and instead we are discussing why astronauts seem to be "weightless" when in orbit.

Also, homework! For everyone: HW: Unit 8 Practice

Additional for Honors: HW: Banked Curves
And a totally awesome online tutorial to help you with that homework can be found here.
