Help!!

If you start to feel like you're falling behind, or maybe my
teaching style is vastly different from your learning style, or
maybe you just want more info on a topic, there are a few
different resources that I would encourage you to look at on
your own. While there are many out there, here are a few that I
think might help you the best:
-HW Rubrics. As I have mentioned (or will mention, depending on
when you read this), all HW problems we do have a solution that
I have done and provide to you. In addition to the HW problems,
most chapters have additional problems that I've done, that I
just didn't assign this year. Trying those problems and looking
at the rubric is often very helpful
-Other textbooks. I have a few other AP texts that might help
for you to just see the information presented a different way.
-Khan Academy. If you are unfamiliar with the Khan academy, you
may want to familiarize yourself with it.
HTML https://www.khanacademy.org/
is the website, and they offer
YouTube style lessons, broken up into approximately 10 minutes
each. Not only would it be great for our class, but math and
other subjects you have too.
-The Physics Classroom. Similar to Khan Academy in that they do
shorter lessons that you can choose, it is also very interactive
in that you can set up your own problems, as well as answer some
of theirs. Here's the link:
HTML http://www.physicsclassroom.com/
-The Physics Aviary. This is an excellent site to reveiew P1
ideas, and you will hopefully use it a TON during the last 3
weeks before the big AP test in May. It is set up as a
simulation of some of the different concepts:

And of course, if you do have problems, feel free to come in and
talk to me, and I'll help you out as much as possible!

Wasn't sure where to ask so I chose her because it's labeled
"Help!", which is what I need.
For the circle lab, of the 10 categories (Purpose, background
info, etc.) which ones do you want us to do for this lab?

Ask someone who was here, as I put it on the board then, but I'm
pretty sure it's the following:
Title
Purpose
Materials
Diagram of one of your experimental set ups
Data
Data Analysis (graph)
Conclusion

On 2.22 my process was to covert mph into m/s and got 26.7. Then
1 gravity is equal to 9.8 m/s^2, so I multiplied that by 7 to
get 68.6 m/s^2. Then since the equation for acceleration is
delta v/ delta t, delta t would equal delta v/a. I then divided
the 26.7(m/s)/68.6(m/s^2) then the units would cancel out to get
.39 seconds to get to 60 mph. Is this process correct?

I think so, I'd have to see your paper to follow the work to be
sure, but that sounds right, and that is the correct answer

As I'm double checking my write up, I want to make sure I have
everything. Anyone have a list of things we need handy with
the?. Thanks in advance.

The Graphing worksheet says make speed vs. time. This should
look different than velocity vs. time graph, right?

Correct. Speed can only be positive, so it's pretty much just
the absolute value of a velocity vs time graph. Notice that
there isn't even room to go below the x axis.

Then how would you find the total change in speed and velocity?
