• Objectives

  After studying the material of this chapter, the student should be able to:
  1. Explain how a simple battery can produce an electrical current.
  2. Define current, ampere, emf, voltage, resistance, resistivity, and temperature coefficient of resistance.
  3. Write the symbols used for volatage, electric current, resistance, resistivity, temperature coefficient of resistance and power and state the unit associated with each quantity.
  4. Distinguish between a) conventional current and electron current and b) direct current and alternating current.
  5. Know the symbols used to represent a source of emf, resistor, voltmeter, and ammeter and how to interpret a simple circuit diagram.
  6. Given the length, cross sectional area, resistivity, and temperature coefficient of resistance, determine a wire's resistance at room temperature and some higher or lower temperature.
  7. Solve simple dc circuit problems using Ohm's law.

The 12 Days of Physics

Work on these problems some should look familiar so if you have notes on them review key concepts...

Pay close attention to the graphs question...

Fc
 New

• The centripetal force is not the agent but the result of other forces.
• Choose a convienient FOR
• Resolve all un cooperating vector into x/y components
•  Write the Sum of the forces for x/y
• Solve for variable in question

USE THE FORCE & Vectors and PSS

ILW 4.1-4.4
work through these noting:

•  PSS and Key Concepts
• you may wish to copy into your notebook ....  (REALLY GOOD IDEA)

Shooting for an A!

Determine of your launcher when launched at 45 degrees.

Post you questions here!!!

Hit me with your best shot!!!

*Only find the components of you velocity for the various angles!!!

Do not continue if you are confused I will post a pen cast that will help explain what is going on in your lab!!!! 

Use the Graph Paper to Sketch an projectile being launched level to level at various angles.
VL=100m/s
Include the range in the diagram
Use the same scale for all launches (Which angle will help you determine this?)
Include (calculate all critical points)
Under each sketch include a Bar Graph like the one in class (Scale should be 0 to 100% of max)
Think about how you want to organize the information in the chart.
         ex1.  VL=100m/s will always be the same regardless of angle
 
         ex2.
                The angle will vary between 0& 90 degrees which would be max

•  So what would 45 degrees look like?

• Graph any quantity that is important to the problem

• Calculation should be done on a separate piece of paper using appropriate PSS strategies! 

• You must include 6 angles

Projectiles

Projectile:

• What defines it?
• Vocabulary:
• trajectory
• hang time
• range
• launch angle
• launch velocity
  
• Print out the Questions below
• Projectile Questions 
• Projectile Simulator
• Objective: 
• 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. 
•  
• Key PSS STRATEGY:
• Treat the motion of the oject as if it were 2 seperate objects
• 1 in free fall (y-direction)
• 2 with a constant velocity (x-direction)
• Key concepts:
• Only the y variables control time
• The y velocity at max height is 0m/s
• If symetrical
• t(up)=t(down)=t(1/2)=1/2t(total)
  
• v(up)=-v(down) 
• a=g @all points

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.
