AP 12 Days of Physics!

Happy Hollidays & winter solstice.
Thanks for those of you who gave gifts totally unnecessary.  As discussed we can not get lazy over the break.  So here are some things to keep you current and sharp.  You need to participate to learn physics.  If not I can't help you.
Read Ch.18.   As many times as it takes post on the blog questions and insights.
 here will be a reading quiz.
On the First day of Physics!

• A Bugatti for Physics.  Bugatti can accelerate 0-27 m/s in 2.6 seconds, which is about a 10.3 m/s/s acceleration.   Assuming a u=.95.  If the answer does not agree give possible explanations.

NOT AS EASY AS PI

Discussion Board:
Objective:
 Devise a method to determine the relationship between length and time of a swing.
Create and interpret a parent graph for the data
Use this Graph PAPER only "CLICK HERE"

Things to think about.  

What shape is the graph?  Is it lnear?

• If your data does not agree with the class discussion the lab is easily redone at home find a bob and a length of string and measure the time for ten swings take the Avg.  It should be clear that it is not a linear relationship..
• Once you have identified the parent graph construct a daughter graph as discussed in class.
• Follow the rules for analyzing linear graphs find the slope and intercept.

Physics Exam Questions
the above link hosts sample MC questions similar to the one used on the Mid-term exam.
Do as many of the questions as you can relating to the topics we covered.

MOTION PROBLEMS 1D

Objectives

• Develop a relational model between the real word the descriptions and the mathematical equations
  

After studying the material of this chapter, you should be able to:
1. State from memory the meaning of the key terms and phrases used in kinematics.
2. List the SI unit and its abbreviation associated with displacement, velocity, acceleration, and time.
3. Describe the motion of an object relative to a particular frame of reference.
4. Differentiate between a vector quantity and a scalar quantity and state which quantities used in kinematics are vector quantities and which are scalar quantities.
5. State from memory the meaning of the symbols used in kinematics:
 x, x_o, v, v_o, a, y, y_o, v_y, v_yo, g, t.
6. Write from memory the equations used to describe uniformly accelerated motion.
7. Complete a data table using information both given and implied in word problems.
8. Use the completed data table to solve word problems.
9. Use the methods of graphical analysis to determine the instantaneous acceleration at a point in time and the distance traveled in an interval of time.
