Another Homework Problem

This is #8 on 2D Motion #1.

HRW94P028 - Projectile fired from ground lands on top of a cliff

2-D Motion Part 3 + Homework Problem

First, the last lecture on 2-D Motion:

Motion in 2 Dimensions Part 3

Also, I worked out #12 on the homework 2-D Motion #1. This is the one about throwing a ball off a building.

More on 2-D Motion

Here is the second lecture on 2-dimensional motion. There is going to be a part three where we calculate more things about this same problem, but I am just too sick right now. Look for it sometime this weekend.

2-D Motion Part 2

Open Ended Lab: Launch Velocity

Today us our first open-ended lab, which means I will not tell you what to do. Here's what we want for the finished product:

America!

Motion in 2 Dimensions Part 1

Homework Monday night is to watch this video and take notes. We'll be doing a lab similar to this problem on Tuesday!

Motion in 2 Dimensions Part 1

Unit Vectors and Motion in Two Dimensions

Please watch this as soon as possible and come to class with questions:

Unit Vectors

I'll post another one sometime tonight that will be homework tomorrow.

#9 on Vector Components

Had the stuff hooked up already, so I did another one:

#9 on Vector Components

#6 on 1-D Motion #2

Someone messaged me that he/she was having trouble on this one, so here we go:

#6 on 1-D Motion #2

#5 on Vector Components

I woke up early enough to do one short problem from your Vector Components homework before my meeting. I'll be home just after three this afternoon.

#5 from Vector Components

Worked-Out Problems

I tried out my new whiteboard by working through a couple of your homework problems.

#3 on 1-D Motion #2: HRW92P027
#5 on 1-D Motion #2: HRW92P044

More Vector Components!

Yesterday for our block period we started working on this vector lab. You can finish this on Thursday. In the meantime, please keep working on the WebAssign assignments that are due Saturday night.

REMINDER: If you haven't yet, please add an email address to your WebAssign account.

Also, I've made a group on Facebook for this class: DVHS AP Physics. I'll update it whenever I update this blog, so those of you experiencing problems with the subscription feed of the blog can get faster updates from the Facebook group.

Vector Components and New WebAssign

Two more WebAssign...assignments...are up: 1-D Motion #2 and Vector Components. These are both due next Saturday night, but I suggest you get started on them sooner than that. A review on vector components is here; please watch this for homework tonight.

First WebAssign!

Yesterday we completed a lab using Vernier motion detectors to graph position vs. time graphs. By tomorrow, Thursday, please sign into WebAssign and attempt the first assignment. I know you can do the first one because we did a similar one in class, plus I made this video last spring when I was testing my capture tablet. For the others, try your best and be ready with questions on Thursday.

Position vs. Time

So what is calculus good for in physics? Well, it's good for finding slopes. Slopes give the rate of change of whatever you're graphing. So what happens when you graph a physics thing, like position, and take it's derivative (find the slope)? More physics things, that's what!

Please watch the videos below for homework tonight. They are not my best...it was a long day. Sorry :(

Derivative of Position w/ Respect to Time

Multiple Derivations of Position - What do they mean?

Calculus Boot Camp!

Homework (due on Thursday): watch these videos about derivatives and integrals! Take notes and come to class with questions; we will do some practice problems during class.

Derivatives
Integrals

You can change the resolution to HD!

Welcome!

This class will be a lot of work, but please don't be afraid; we will have a lot of fun, too. This is my first attempt at a "flipped" classroom, so please give me feedback on what is working, what is not, and what we can do better or what else you need to be successful. I am a student just as much as you are.

I will use this blog to post lectures you need to watch for homework as well as reminders for tests, homeworks, and other assignments. Whenever I manage to make extra videos working out a specific problem, I will also post here. I suggest subscribing with a feed or by email using the boxes to the right so you don't miss any posts.

For those of you that want to use old resources but don't want to search through this blog, I will also be archiving everything at sites.google.com/site/desertviewapphysics/, organized by unit.

First assignment! Read through the syllabus and safety contract and return the safety contract tomorrow, plus log into WebAssign and change your password. Instructions for logging in are the topic of our first video lecture!
