• 2) break vectors into components, where the parallel component of weight is mg(sin θ);
• 3) write Newton's second law for parallel and perpendicular components; and 
• 4) solve the equations for whatever the problem asks for.

 Review Strategy:

• Read section reviews for chapters covered
  
  •  find MC questions that illustrate topics.  
    
    • If you understand what the correct answer is and why move on, if not review, post, and correct your misconception

Period 9 MID TERM REVIEW

Regents Test

Extra Credit T/F Review Test
You will be required to complete a scan-tron "No whining!"

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.
Here are some sample questions:

You are permitted to bring one side 8.5x11 inch paper with hand written equation sheet you may include diagrams but no notes.

There is no curve!!!
It is a Pre determined standard.
80 correct = 100
70=90
60=80
50=70
48=68

 How to Eliminate Choices:

•     What UNIT should the answer be in?  Especially for those questions with no numbers.  Look at the arrangements of the variables to find which choices are in the correct units (dimensional analysis)

•     Should the answer be larger or smaller than a given value in the problem? (increase/decrease/relationship problems)

•     For graphs, think about probable shapes and slopes.  Where the line goes to zero is often a good indicator of correct or incorrect choices.

•     For those questions that read “Which of the following…”  Be extremely careful of the word NOT and be sure to read ALL the choices before picking one.  Many mistakes are made when a student picks choice A after reading it and never even gets to B through E.

•     Predict the sign of your answer (+/–) to eliminate choices

•     Predict the possible directions (for currents, vectors, etc.) to eliminate choices

HONORS PHYSICS P9 2 Dimensional Motion

Key Strategies:

• divide the problem into 2 linear motion problems using PUKE
• one for the x and 1 for the y
• Time for the x&y are the same {the motions are occurring independently and simultaneously}
• Solve for time using PUKE"S" in either the x or y and apply it to the other direction.
• You are not learning anything new 

HW:  Since we are not in school today work on any 3 problems and post ideas and question and solutions to the blog.

AP ELECTRICTY Part 1 Electrostatics

Objectives

After studying the material of this chapter, the student should be able to:
1. State from memory the magnitude and sign of the charge on an electron and proton and also state the mass of each particle.

2. Apply Coulomb's law to determine the magnitude of the electrical force between point charges separated by a distance r and state whether the force will be one of attraction or repulsion.

3. State from memory the law of conservation of charge.

4. Distinguish between an insulator, a conductor, and a semi conductor and give examples of each.

5. Explain the concept of electric field and determine the resultant electric field at a point some distance from two or more point charges.

6. Determine the magnitude and direction of the electric force on a charged particle placed in an electric field.

7. Sketch the electric field pattern in the region between charged objects.

8. Use Gauss's law to determine the magnitude of the electric field in problems where static electric charge is distributed on a surface which is simple and symmetrical.
