Lab Notebook due Monday (which includes): || Notebook Entries: by midnight || Read and consider the material here. Your weekly discussion post should include a comparison of the different ways to show the same motion. || ||
 * Graph Matching Lab
 * Part II # 7 - Describe how you would walk to produce target graph
 * Part III # 13 - Describe how you would walk to produce target graph
 * Analysis questions # 2 - 8
 * Describe how to spot acceleration on a position vs. time graph
 * What does acceleration look like on a velocity vs. time graph?
 * Acceleration Lab

 * 9/12 || The science dept. is on a field trip today, so WATCH these videos in class & TURN in a description of how you might put the ideas together & do an experiment to prove Walker & Billy wrong. Remember - you just have to describe the experiment so you can impress me with your creativity. For Walker & Billy - your experiment should describe a way to prove each other right.
 * 1) Balancing a pencil

 * || Here is a link to help you think more about measuring & describing motion. How would your relative position change your graph? ||

 * 9/10 || Spending time in class with discussion is good.....but it puts us behind a little. SLOPE on Velocity versus Time graphs gives us information about acceleration, but you can also use AREA to check yourself on displacement. ||
 * 9/9 || Quiz on position versus time graphs - try these for practice. POST questions or see me before class on Monday to get help before the quiz. Here is a follow-up to consider. ||

 * Experimental procedure
 * Part II # 7 - Describe how you would walk to produce target graph
 * Part III # 13 - Describe how you would walk to produce target graph
 * Analysis questions # 2 - 8
 * Describe how to spot acceleration on a position vs. time graph
 * What does acceleration look like on a velocity vs. time graph? ||
 * 9/4 || Acceleration questions due. Here are some helpful links:
 * Hot wheels track
 * Ticker tape Diagrams ||
 * 9/2 || Introduction to motion formulas in class ||
 * 9/2 || Lab Notebook check
 * Index & Vocabulary sections setup
 * Descriptions of how measurements were taken in BOTH motion experiments
 * Data from BOTH motion experiments
 * Written description using kinematic vocabulary that compares the three groups in experiment 1.
 * Sketches of position vs. time graphs which identify:
 * Constant rightward velocity
 * Changing velocity to the right (acceleration)
 * Constant leftward velocity
 * Changing velocity to the left (acceleration)
 * Speeding up (positive acceleration)
 * Slowing down (negative acceleration)
 * Motion man notes - what did you learn about a position vs. time graph?
 * media type="custom" key="26484634"
 * Conclusion - how to analyze position versus time graphs ||
 * Due 8/29
 * 8/29 || IN CLASS: login to student mail (from HCS homepage) using your HCS network ID & complete this questionnaire before doing the Moving Man Lab. [LOGIN using username@student.haywood.k12.nc.us] ||
 * 8/27 || "In physics, the use of positive and negative always has a physical meaning." notes here Use the ticker-tape method we learned on Monday and modify the experiment to show positive and negative motion. ||
 * 8/26 || What can a position vs. time graph tell us about an objects motion? We did one experiment (with 3 trials) - which of these graphs does yours look like? {see pictures below} ||
 * Friday (8/22) || Relative Position - video shown in class & here is the conversion worksheet
 * Due 8/22 || Read and consider the material on this website and provide your own example on the discussion board ||

Unit 2 - 3 Two Dimensional Motion & Forces Oct. 1 - Nov. 25
(back to top)

Octophant will present some time before Thanksgiving Break
 * || [[file:Projectile Project.pdf]] ||
 * || Presentation Schedule:
 * Weds - Destroyers
 * Thurs - M & M & Winners
 * Fri - J squared, JacoBan, Grapemeisters
 * Mon - ChiefDan & RichAd
 * Tues - Bavarian Illuminati & Spudnik

HW due Monday 11/25 ||
 * 11/13 || Use this link to verify your projectile calculations. ||
 * 11/10 || See these notes on centripetal force to help with the case study. ||
 * 11/6 || Use this tutorial to help analyze a practice video. Bring in your own video (or post it to your project page) and try it out!

Here is the link for friction coefficients (it was buried on the discussion board) || Check out these videos: AND Projectile Project Groups work on an experimental plan. Moving Man DUE Friday 10/31. Lab Notebook due Thursday 10/23. ||
 * 10/31 || How to measure force? It seems to be a common question........ is there a formula for that?
 * Nerd-A-Pult
 * Projectile Launch ||
 * 10/29 -10/30 || We will practice our understanding of Newton's Laws. Here are links to reading material and practice problems from the online textbook. We will have a quiz on Newton's Laws 11/7.
 * Force & Acceleration
 * Two Problems to check your understanding (scroll to bottom)
 * More Practice
 * Terminal Velocity
 * Newton's Third Law ||

 * 10/21 -10/22 || Tackling vector word problems with Newton's Second Law & finish work on Picket Fence Lab.

Law 1: An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction [|unless acted upon by an unbalanced force].

Law 2: The acceleration of an object is dependent upon two variables - the [|net force] acting upon the object and the mass of the object.  **OR F=MA** || || Measuring Gravity from the Band Tower. Practice with video analysis. I think we (I) forgot something really important here. || || ||

 * 2) Identifying components of a resultant vector
 * 3) Using trigonometric functions to determine magnitude & direction ||
 * 10/13 -10/14 || Picket Fence Experiment - measuring acceleration due to gravity. Here are the lab instructions. I will have the materials, but you will construct the picket fence according to these instructions. Here is what you should have in your notebook:
 * 10/9 || Practice using trigonomic functions to find the component values of a vector. Remember, the horizontal and vertical velocities are INDEPENDENT! Check out the diagram here. ||
 * 10/7-10/8 || Here is where the math happens........ let's go back to our motion detector data (the 6 different setups).
 * Use equation 4 to calculate final velocity for each.
 * Draw a vector diagram for experiments 1, 3, and 4. What forces do the two vectors represent?
 * Does your velocity calculation change if you use equation 1 or equation 3? Should it be the same?
 * What variable in the experiment was never measured? [Think elephant & feather] Should we have measured it? Why or why not? ||
