### Video Analysis: No Strings Attached and Strings Attached

This tutorial will give you the basics on video analysis with logger pro.

Then you'll need to analyze each of the two videos below:

No Strings Attached

Strings Attached

IN CASE I DIDN'T MENTION IT IN THE VIDEO, YOU DON'T HAVE TO PUT A DOT ON EVERY FRAME, YOU CAN SKIP AHEAD A COUPLE OF FRAMES BETWEEN DOTS AND IT WON'T HURT YOUR GRAPH.

Bring a print out of the velocity vs. time graphs for your video analysis to class on Thursday. Additionally, draw FBDz for the strings attached video for (1) the time before the blower has been turned on, (2) for the time a short while after the blower has been on, and (3) for the time after the mass has hit the floor. Additionally, you'll need the FBD for the no string attached video.

### CAPM Carts Up and Down Ramps

## Cart Up and Down Ramp, Period 1

From the Areas of the Velocity v. Time graph and Acceleration v. Time graph, we get Evan's Law and Carter's Law, respectively.

## Cart Up and Down the Ramp, Period 2

From the Area of the Velocity v. Time graph and the Acceleration v. Time graph we get Emma's Law and Mackenzie's Law, respectively.

### Essential Understandings for the BFPM

Unit 3 Balanced Force Particle Model (BFPM)

3.1 I can
construct a system schema to determine all of the interactions a particle is
experiencing.

3.2 I can identify and include all the necessary
information when representing forces.

3.3 Weight and Mass – Can distinguish between the
gravitational force on an object, and the mass of the object.

3.4 If the forces on an object are balanced, I can
use force diagrams to determine unknown forces acting on the object

3.5 I can describe forces in terms of interactions
between two objects, and can utilize force pears to determine values of unknown
forces acting on an object.

3.6 I can represent the forces on an object with dot
and arrow (Free Body) diagrams.

3.7 I can identify conditions which indicate the
forces on a particle are balanced.

3.8 I can determine situations in which the BFPM
clearly applies, and situations in which it clearly does not apply.

### Essential Understandings for the Balanced Force Particle Model

As we work our way into the new model, here are the relevant Essential Understandings. I post a more complete list as it becomes necessary.

BFPM

1)
System
Schema

I can
use a system schema to show an appropriate choice of system, identify objects
that interact with it, and determine the appropriate number of interactions.

2)
Force
Diagram - Labeling

I can
draw/interpret force diagrams, labeled with force type, feeler, dealer, and equality
marks, with the appropriate number of forces, and precisely showing the
direction and relative magnitude of each force.

3)
Weight
and Mass

I can
distinguish the difference between weight and mass. I know the value and units for the Earth’s
gravitational field strength near its surface.
I can use it to calculate mass or weight.

### Essential Understandings for the First Two Units

Here are the Essential Understandings for the first two units we've studied in physics.

For the Lab and Data Analysis unit, most students have demonstrated mastery of 1.3 and 1.4, therefore those understandings are not likely to show up on a whole class quiz again. Most students are still developing their understanding of 1.1 and 1.2, so those will likely show up again on future quizzes. 1.5 will be continuously assessed throughout the trimester.

Unit 1 -Lab and Data
Analysis

1.1 Graph
Analysis – Equation

I can
find the equation of a linear function without the aid of a graphing program.

1.2 Graph
Analysis – Variable

I can
solve for the independent or dependent variable in a linear function.

1.3 Graph
Units

I can
find the units of the slope and vertical intercept for a linear relationship.

1.4 Physical
Meaning

I can
interpret the physical meaning of a linear equation (slope, vertical intercept,
independent variable, dependent variable, etc) in a clear jargon-free sentence.

1.5 Units

I can
assign the proper unit and correctly convert units.

For our second unit, we are still just beginning our study of most of these understandings, so they will make up the bulk of the quizzes for the next few weeks.

Unit 2 - Constant Velocity Particle Model

2.1 Break
The Model

I can
determine situations in which CVPM clearly applies, and situations in which it
clearly does not apply.

2.2 Position
Graph - Analysis

Given a
position graph, I can sketch a velocity graph, motion map, and describe the
motion in words.

2.3 Position
Graph - Velocity

I can find
the velocity of an object using the position vs time graph.

2.4 Average
Velocity Versus Average Speed

I can distinguish
the difference between velocity and speed and calculate both on a position vs
time graph.

2.5 Velocity
Graph - Displacement

I can
determine the displacement (change in position) for an object using the
velocity vs time graph.

2.6 Velocity
Graph - Analysis

Given a
velocity graph, I can sketch a position graph, motion map, and describe the
motion in words.

2.7 Motion
Map - Analysis

Given a
motion map, I can sketch a velocity graph, position graph, and describe the
motion in words.

2.8 Word
Problems

I can
solve word problems using the constant velocity particle model.

2.9 Distance
Versus Displacement

I can
distinguish the different between distance and displacement and calculate both
on a velocity graph and/or a position graph.

### Online games to build your graphing intuition!

These online games can be used to help buff up your understanding of graphs of motion!

Super Ultimate Graphing Challenge (Click on "Graph Game")

Also, if your reasoning score was less than a 7/13, it might be a good idea to give this game a whirl. The password was given in class, and you should try to get through the first couple of levels over the next couple of weeks.

### Enjury Conservation Retake Practice

Use the Phet Enjury Sk8t Park (a lot of enjuries happen at sk8t parks, after all) to improve your understanding of Conservation of Enjury.

Focus on LOLz and Pie Chartz. When is the energy stored in motion (Ek) at a maximum, when/where is the energy stored in gravitational interaction (Eg) at a maximum?

### Enjury and Pain Storage

Here's a video by a fairly bright guy called Dr. Richard Feynman (if it doesn't go directly to the 22 minute mark, go on and skip ahead to that point). He's your new favorite physicist. He's using an analogy for this thing called Enjury that we were talking about in class the other day. He pronounces Enjury a little differently from you and me because he was born in Brooklyn, and most of you weren't.

We'll use his analogy of conserved blocks to represent Enjury in our representational scheme. The representational scheme we're using is called a LOL diagram. Watch this video to learn how to properly set up a LOL diagram. Just a heads up, I stole this worksheet from my friend Kelly. She spells Enjury differently from us because she teaches in Manhattan, and most of us don't.

Use your understanding, gleaned from these videos, to begin work on the packet. Think about some of the different ways Enjury can be stored, in motion, in a gravitational interaction, in the stretch or compression of a spring, in chemical bonds of gasoline, in thermal vibration of atoms making up an object, in sound, in light.... whoa, there are a lot of different ways to store pain, and then later use it to hurt others!
