Determining a Spring Constant

For IB Students - this is your chance to practice what IB thinks is the proper way to determine a value and uncertainty.

4:59 Spring Constant Graph Part I

If you choose this option for your energy lab, you are going to get a spring, gather data of your own choosing (Work all by your lonesome) and turn in the following:

1. A beautiful data table that is beautiful in all the ways I talk about in the above video. (Watch through about 2:08)

2. A nice graph like the one we made in class. You could use Excel or Google Spreadsheets to do the BFL, and the error bars, but you will need to schmooze the max and min slope lines yourself.

Here are the videos for how to make the graph with graph paper: (From what we did in class)
