This week, we are introduced to Sir Isaac Newton's laws of motion and the concept of a force. We will be using his three laws for all of our work this week, and it will stay with you throughout the rest of the year, so become good friends with these ideas! We also distinguish between weight and mass and introduce the concept of inertia.
The above video covers Chapter 4A and 4B, introducing you to the basic concept of vector measurements. We cover concepts including graphically adding and subtracting vectors and how to measure their angles against a Cartesian coordinate system or a map.
The above video covers how to solve vector addition and subtracting using trigonometry, which is more accurate and (once you're comfortable) easier to do. It's time to blow the dust off of your triangle geometry! This covers section 4C.
Welcome to Week 3! We're looking this week at how to analyze motion with a set of equations. We're covering Section 3B this week, and you'll have to use these equations a number of times. Remember, you'll never have to memorize equations. You just need to know how and when to use them. Pay attention to the examples I give and the examples in the book. Use the comments field below for any questions, and I'll answer them as soon as I can. See you in class!
Alright! It's time to get started. This is the first flipped lecture for our course, "God and the Nature of Science." If you need to pause to copy down the info on the slides, feel free. Educational videos on youtube need to be less than 15 minutes long, so I won't leave the slides up for more time than it takes to explain them. If you have any questions, you can post them in the comments section of the blog page below, and I'll either address them here or in class.
Bless you! See you in the morning.
Lecture #2: Review of Measurements and Math
Lesson #2 is a whirlwind tour through chapter 2. We're only going this fast because ALL of this is review. If you have any questions, please post them to the comments section below, and I'll address them, either in class or here, depending on when I see it. God Bless you! See you tomorrow.
Additional Resources for this week:
A review of significant digits and unit conversions from Crash Course Chemistry (You saw this last year):
Another review of significant digits that boils it all down to a few very simple concepts:
The above video walks you through chapter 3A, describing terms with regard to motion. We talk about how to describe motion with regard to a reference point, the difference between scalar and vector measurements, distance vs. displacement, speed vs. velocity, instantaneous vs. average speed, and acceleration.
Here are some additional graphs that help you see the relationship between displacement, velocity, and acceleration:
Let me know if you have any questions! We'll see you in class.
Welcome to Mr. Alley's Physics class blog page. Here, I will post many of the activities we do in class, as well as all of the at-home lectures that I either create or link to for your required activities. Check back here frequently, as new content will be posted every few days.
If you have any questions about any of the posted assignments or lectures, feel free to use the comments field below, and I'll follow up with you, either here or in class.
Many of the resources I post here will be Google docs, Google slides, or YouTube videos, all of which are Google's products. If you don't have a Google account (Google+, Gmail, YouTube, etc) you should get one. It will make your life easier with regard to viewing items I post.
Also, I have a shared upload folder on my Google Drive that you can use to turn in any assignments that you choose. This will come in handy for electronically generated projects that can't be printed (videos, slide shows, etc) and will also be a lifeline for you if you printer goes down and refuses to print your papers. The student upload folder can be found here. Again, you'll need to be signed in to Google to use this folder. You can also install Google drive on your desktop and have this folder in your normal browser. This way, you can just drag-and-drop any assignments you would like to electronically turn in.
This is a flipped class, meaning that almost all direct instruction will happen here, electronically, and almost all the application and practice will happen together in the classroom. There will be some variation to that, but not much. The goal is to maximize the amount of time I can spend with you doing the work and empower you, as much as possible, to become an independent learner.
