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

Conceptual: Forces Study Guide

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

Teacher Out

I've off at a training for MESA so you're on your own today. Conceptual class (p.1), please work on Friction II and also turn in last night's homework. Honors classes, please work on Inclined Planes I.

Solving Newton's 2nd Law Problems

The demo mentioned in the bellwork was pulling a tablecloth out from underneath some dishes.

First we walked through a standard problem involving Newton's 2nd Law:

At this point we practiced on the worksheet Net Force and Acceleration (link to the back). I don't have an electronic version of the front. You also received Forces Practice for homework. This contains conceptual problems similar to what you'll see on the next test.

For the Honors classes, at the end of the period we did the same practice problem as before but made the pulling force at an angle. Notice that the basic procedure does not change, but when finding the net force in each direction we have to break up the angled force into its x and y components. We also skipped the stuff in the y direction because we already knew the acceleration in the y direction is zero, so net force in the y direction is zero.

Newton's 3rd Law

Today we looked at some consequences of Newton's 3rd Law, including the normal force. Homework is Newton's 3rd Law.

Newton's 2nd Law

Today we used your lab results to derive the equation form of Newton's 2nd Law. We also did a few practice problems. Homework is Newton's 2nd Law.

Force, Mass and Acceleration Lab

Today and tomorrow we are using a lab to discover Newton's 2nd Law. The conceptual class is split in two:

The Effect of Mass on Acceleration
The Effect of Force on Acceleration

The honors classes have one big lab:
The Effect of Force and Mass on Acceleration

The setup diagram and bellwork are below.

Newton's First Law

Today we used some hypothetical and real-life examples to analyze Newton's First Law.

Homework is below.

Honors: Forces Study Guide Answers

Here are the answers for the study guide that I posted on Wednesday. Your test is Monday!

Honors: Forces Unit Study Guide

Our first test of the semester will be on Monday. Below is the study guide; I will post answers later.

Forces Study Guide

Honors: Forces Practice

Today we are practicing some conceptual problems. Several of these are from last semester, so I thought we could use a refresher before adding friction into the mix tomorrow.

Abridged answers!

Honors: Three Practice Problems

Today we're just going to practice three problems: a box on a flat surface with no angled forces, a box on a flat surface with angled forces, and a box on an incline. All of these are frictionless.

Honors Forces II (note that the paper given in class has a drawing for each problem)

Conceptual: Unit 7 Study Guide

Your test for the forces unit is on Friday! Here is your study guide:

Unit 7 Study Guide

I will post the answers tomorrow.

Honors: More Inclined Planes!

Today we finished our practice problem involving two bodies connected by a rope on an inclined plane. Below are the final results.

Homework is Inclined Planes I

Honors: What To Do With Angled Forces and Ramps

Today we started talking about how to deal with forces that are at an angle. We also started a problem about a box on a ramp, but we did not finish.

No homework tonight.

Conceptual: Newton's 3rd Law

Newton's 3rd Law is my favorite, so please don't misuse it! It only applies to forces, not actions of people.
Homework is Newton's 3rd Law - it is a small paper, so don't lose it!

Honors: Newton's 3rd Law

Newton's 3rd Law is my favorite :) Homework tonight is a small paper - don't lose it!

Newton's 2nd Law

Bellwork and notes were the same thing today (below). Here is your homework:

Newton's 2nd Law

Please remember to turn in your lab!

Honors: Newton's 2nd Law Lab Continued

Hey guys! We're still working on our lab, but we spent the first 10 minutes of class on a bellwork that will help you process your data. The full lab report is due Monday, but if you finish early please turn it in early.
