Vectors (AP PHYSICS)

Objectives

After studying the material of this chapter, you should be able to:
1. Represent the magnitude and direction of a vector using a protractor and ruler.
2. Multiply or divide a vector quantity by a scalar quantity.
3. Use the methods of graphical analysis to determine the magnitude and direction of the vector resultant in problems involving vector addition or subtraction of two or more vector quantities. The graphical methods to be used are the parallelogram method and the tip to tail method.
4. Use the trigonometric component method to resolve a vector components in the x and y directions.
5. Use the trigonometric component method to determine the vector resultant in problems involving vector addition or subtraction of two or more vector quantities.
6. Use the kinematics equations of Chapter Two along with the vector component method of Chapter Three to solve problems involving two dimensional motion of projectiles.

Period 7 only

Group the smaller groups into larger ones  what do they all have in common.  Use the relationships to write a sentence or two about what is physics.  Post questions about groups and names.  Do not post your final answer to the blog.
 Put in your notebook and bring to class on Tuesday.

Writing an Abstract

Summarizing the lab report

Summarize each major section of the lab report--Introduction, Methods, Results, Discussion, and Conclusion--in 1 sentence each (two if a section is complex). Then string the summaries together in a block paragraph in the order the sections come in the final report.
More Help:
You can think of the Abstract as a miniature version of the whole lab report. Read each section of the report and boil it down to a sentence. This means that you need to determine the most important information in each section.
  • Here are some suggestions for what to include in each sentence of the Abstract:
    • Introduction: research problem of the lab; hypothesis
    • Methods: a quick description of the procedure
    • Results: statement of the overall findings
    • Discussion: judgment about hypothesis; solution for problem
    • Conclusion: what you learned from doing the lab
  • Put all these sentences together into one paragraph with the heading "Abstract."

Things That?

  • students will be able to identify the components of a scientific observation and contrast with non scientific observations
  • replace transform non scientific observations and make them scientific.
  • Recognize the difference between qualitative,quantitative, subjective and objective and what characteristics an observation has
  • Investigate and create operational definitions based on observations
  • Use observations to develop the need and understand the importance of measurement
  • use observations to organize things in a clear and consistent manner
  • use observations to construct hypothesis
    • identify strategies for looking for organization
    • binomial searching algorithm 
  • use and understand a graphic organizer (T-Chart)
  • Use the T chart 
    • to make observations as to trends
    • extrapolate (evolution)
    • interpolate (missing link)
    • summarize
Several Questions:
Do not look up the answer it is useless in this exercise. 
Write down your observations of the characteristics of fruits and vegetables use that to define them and determine the difference!

You should make a things that chart to answer your questions.

What is the difference between a fruit and a vegetable?  So what is a Banana?


What is a duck billed platypus?


Is a virus a living thing?

ABC GUM LAB AP Physics B

LABORATORY AND EXPERIMENTAL SITUATIONS
These objectives overlay the content objectives, and are assessed in the context of those objectives.
1. Design experiments
Students should understand the process of designing experiments, so they can:

          a) Describe the purpose of an experiment or a problem to be investigated.

          b) Identify equipment needed and describe how it is to be used.

          c) Draw a diagram or provide a description of an experimental setup.

          d) Describe procedures to be used, including controls and measurements to be taken.

2. Observe and measure real phenomena
Students should be able to make relevant observations, and be able to take measurements with a variety of instruments (cannot be assessed via paper-and-pencil examinations).

Ap Summer assignment #1 Ch.2 Problem Set

Here is an alternative link to  a downloadable PDF for the Problem Set</>
This is paramount to your success. If you can not find time to do this you really do not want to be in Physics B. I can. Not stress this enough. It is like working out for you to reap any benefit you must push yourself as hard as possible. It will be difficult at times but that's when you know it's working!
You may and should discuss questions you have here on the blog. Be sure to include the question # and the issue you are having.

Assignment details.

  • All problems should be done in a composition notebook with the first 5 pages left blank for T.O.C.
  • Each entry work date should be note with start and end times with your name in the upper right hand corner---->. First initial and last name is acceptable.
  • Answers are to be recorded on google form.
  • You Should be devoting  a minimum of 2 hours a week to this or 5 problems a day.   If you work for 2 hrs and get all the problems done Great.

Waves Sound & Light

Waves TEST Due Monday


  • Objectives
    • After studying the material of this chapter, you should be able to: 

      •  State the conditions necessary for resonance. Give examples of instances where resonance is a) beneficial and b) destructive. Explain how damped harmonic motion can be achieved to prevent destructive resonance.
      •  Distinguish between a longitudinal wave and a transverse wave and give examples of each type of wave.
      • Calculate the speed of longitudinal waves through liquids and solids and the speed of transverse waves in ropes and strings.
      •  Calculate the energy transmitted by a wave, the power of a wave and the intensity of a wave, across a unit area A.
      •  Describe wave reflection from a barrier, refraction as the wave travels from one medium into another, constructive and destructive interference as waves overlap, and diffraction of waves as they pass around an obstacle.
      •  Explain how a standing wave can be produced in a string or rope and calculate the harmonic frequencies needed to produce standing waves in string instruments.
