The idea of forces is on the exam... Most importantly that they are vectors and behave as such.
The total FORCE= Net Force=(Fnet)=ma
Or simply Fnet=ma

There are only to possibilities when it comes to Fnet:
They add up to zero (equilibrium)
Or they don't and the object accelerates.

Tracker APPB

Link for tracker is posted on twitter:
AP and anyone else interested in some extra credit.
Due Monday
Write steps on how to use tracker:
Objective:

1. Import a video of a simple exhibiting simple motion.
2. use tracker to autotrack the potion of the object
1. create a graph of this in tracker
3. email me the graph by Monday

APPB:FBD:

• Copy all diagrams into your notebook. 
• Draw the FBD for all situations.
• Discuss on the blog.
• Also I crated a Google+ Hangout link on the assignment so you can work together by use of a microphone or webcam

Projectile Problem AP

Identify the keys to the problem.

Solve for Thursday.

Graphical Analysis using Excel

• Do not have excel?
• Download Open Office 
• you do not have to fill in the form just wait download will proceed

•  Go to Clemson Physics excel tutorial.  

• There are some subtle differences between open office and excel but the translate very well.

• Graph your data from easy as Pie compare that to your hand graph.
• all the rules for graphing still apply but now must be typed...

Phresman Last Week Q1

We have one more quest this MP.
It will include the Scientific Method-Related vocabulary
Powers of 10
Scientific Notation
Significant Figures Precision and accuracy

Easy as pie

Measure 10 circular objects circumference and diameter.
Measure is the key word. Use the objects I showed you in the pretzel container...

Phreshman Physics Project

Some of have emailed me directly, but you can post thoughts here.

APPB: Active Physics

Please post realizations questions and important ideas here as it pertains to projectiles and 2-D motion.

AP PhysicsB: Running Lab & Test

What are the key ideas.
What equations would model the event?
What would the graph look like for
Position/velocity/Acceleration

Build your own unit.

Post your ideas for units here.  Rate and discuss others students  units.  Get ideas on how to make crazy units.

Upcoming Test. Question

How do I prepare for the test?

• Make a list of things that. 
• for example words/vocab 
•  Group them together determine similarities and difference most importantly relationships. 
• Why are these words important in our pursuit of science.
•  Can you use the word properly in a sentence? 
• Can you give examples to help illustrate the word or how the meaning of the word is different from other terms
• Can you apply and descibe how the ideas.
• Just giving an answer is worth only about 10% (if it is correct)
• The process and clear communication of the process is worth 90% (even if it is in correct)
• Practice:
• Choose any to rolls from petals and analyze them (ignore all previous conclusions and observations about the rules)
• be clear about similarities and difference ect.
• what can you deduce/infer
• make a statement about what can be determined from the observations.

Things that?

Is a virus alive? Use your powers of observation and organization to determine. "Things that?".
Hint: determine the characteristics of living things by making observations. Then look at the characteristics of a virus and decide wether it meats your criteria for living things.

Momentum take home Quiz

For the value of y in #3 use 31.3 m/s opposite the direction of the initial vbof the ball.

i.e. Vfball= 31.3 m/s

AP:hydroponics

Determine the maximum number of plants that can be supported in a hydroponics system. Given the parameters from class.
Density of foam- 100kg/m^3
Mass of plants-.5kg
Volume of foam- .012m^3
Radius of opening in foam for plant r- .08m
Key to solution.
Draw a picture
Create a fbd
Write an equation For sum of forces interms of the number of plants
Set sum = 0
Solve for # of plants
You should include at minimum the step listed above. A nice picture with some color would be awesome.
Oh and state the objective first!

Right Round the Lab!

Mid Term Review

http://www.nysedregents.org/physics/
This is an excellent source of review questions for the Midterm. The types of questions listed under the January Exams are similar to the 100 mc questions on your exam. Do as many questions as you can. If you have question, post it hear hopefully someone can help. Be sure to post the year and question #.

Projectile Problems Motion in 2-D

Honors Physics please use this to discuss and post question relating to the problem set.

Do not copy or share this with any students outside of class. This is a dedicated use. Failure to comply will be subject to both disciplinary and honor code violations.

HW CH.5

To puke or not tonpuke? all problems u most puke, if you want full credit... Also the problem set is only due the day after the last posting date which is wed. (today)
Physics is not about the answers but how you get the answers and showing your work. That's why as stated in class the final answer is only 20%. (s)
Practice like you play. If you don't do the hw like we outlined in class, you don't do it on the test either and that is what you are being graded on.

Assignments & Extra Credit

All students in my honors classes who did not check the website for updates and assignments will receive for a hw grade of 0 for "Not as easy as pi". You will however receive a grade for the completion an analysis of the lab. In addition the test will be on Friday of this week. This is not a punishment but a reality of what happens when you don't check the blog. I needed you to do the assignment, that's why I posted it. I am extremely disappointed. Please do not let me down again.

If you checked the blog you would know as well that extra credit has been closed for over a week. So I can not award extra credit after the cut off. It would be much easier for me not to do extra credit at all.

Marking Period 2

Hey it's not to late to think ahead. Create a Google a gmail account and a google calendar. It will allow you to schedule times for extra help.

Extra Credit closed mp1

AP Physics

Hey guys. I might be out for a while. You need to really hunker down and read ch.3 2D motion.
Main Ideas
Time does not have direction
Therefor tx=ty
Set up all problems in x and y as separate problems. (you will be able to solve for time in one 1 of the directions)

Finally: the motion of the x does not affect the motion in the y. They are independant!

Check:

A bullet is dropped and a bullet is fired horizontally from the same height.
Which hits the ground first? If you said the one that is fired, reread the above, I you said the dropped one reread the above.

Popper Lab

Things to think about:
What is a pop?
How long is a pop?
What is the maximum height of you popper?
What is the velocity max of your popper?

Why can't you use a stop watch to get the time?

What is the acceleration of your popper?

Easy as Pie

Hey questions post them here.

Can I use 2 different scales for each axis?
Yes, while it is not preferred sometime it just make sense and is necessary.

CH.2 1-D KINEMATICS

Things to remember:
acceleration negative or positive?
Define your frame of reference
Vectors have direction!
The sign of the "vector quantity" indicates its direction.

What is Physics?

  I got a couple emails.  SO if you have questions you can post them here. 

• The most important thing is that you have words @ least 25.  The more words the better.  
• Now organize them into groups.  
• It would probably be easier to do this on the computer because you can easily revise your groups
• Now look at your groups.  Whats the big picture?  What is physics based on your organization of terms?

First Days Keys to success.

It is important that you begin with the end in mind.
You will get exactly out of this course what ever you are willing to put in to it.

At times Physics in general can be difficult but, if you do things just to get them done what have you really accomplished.

The key to success is to try and learn and UNDERSTAND Physics when doing assignments and reading.
If you do this it will make things easier.
You will have questions when if you follow the above, I will be happy to answer those questions.
