### Codes for Feedback

Here's a link to the doc that lists all of the feedback codes you might see on your lab work, quizzes and tests.

To be faster more efficient and avoid feeling like Bill Murray in Groundhog’s Day having to write the same comments over and over again on multiple lab reports, I’ll be using the following codes on your work to deliver this feedback.

Please note, there is a reason that I’m giving you this feedback, and allowing you to resubmit for full credit, instead of just giving you an 8/10 or 7/10.  I have high standards for your work, and I know that you can meet those standards.  Do me a favor, and have someone else review your work before you re-submit it so I don’t have to ‘Dislike’ it more than once (see above note about Bill Murray)!

#1 You need to base your slope calculation on your OK Fit line, not your data points! (why)
• Be certain to share your work showing how you determined the slope, including units.

#2  Equation Format!
• Be certain to use the axis variable (the thing!) in place of ‘x’ and ‘y’!
• Put the correct units on the slope and vertical intercept!

#3  Your OK Fit line should be drawn using a ruler or straight edge, not as a connect the dots puzzle!  It shouldn’t be drawn through any specific dots, it is a “don’t connect the dots line.”

#4 Scale your axes continuously from Zero, no breaks!

#5  Plot your data on your graph, and make sure to maximize the size of the graph!  Don’t just tuck it into one corner of the grid.

#6  Label your axes and be sure to include the correct units of measure.

HDYK?  “How Do You Know?”  You seem to have made a jump in reasoning, please provide evidence or argument to support your claim.

SW?  “So What?”  Why does that matter?  You’ve stated something, but you haven’t made it clear why that statement is relevant to the problem.

### How to deal with the curvy position v. time graph

This video will walk you through the process of creating a velocity v. time graph based on your curvy position v. time graph.  Please have your graph of velocity v. time ready to share in class tomorrow.

### Air Track Videos for Analysis

Here are the videos for you to download and analyze using the Logger Pro Jedi Skillz discussed in the previous blog post.  You'll need to craft velocity v. time graphs for both videoz.

For the strings attached video, the glider is interesting until just before it smacks into the bumper on the right side of the air track.

Strings Attached

For the No Strings Attached video, the glider doesn't become interesting until it has started moving to the left of frame, it remains interesting until it bounces off the other end and gets back to the middle of the air track.

No Strings Attached
