Is there any physical property (or properties) that all of your rectangles share in common? Explain.

Part I: Now go to the filesystem, open your period's folder, and open the EXCEL file entitled 1-rectangles. Immediately rename the file by saving it with the new title Rectangles_LastnameLastname.xls where the two last names are those of you and your lab partner. In the columns provided on the first worksheet (tab) input the data from your data table.

What is the name of your group's EXCEL workbook?

What is the coefficient of restitution, R2, for your graph?

What is the shape of the EXCEL graph displayed using your data?
	straight linehyperbolaparabolaellipse

According to your EXCEL graph, what is the relationship between the length and width of your rectangles?
	directly proportionalinversely proportional

Part II: Now complete this following second data table and graph its values on the second worksheet (tab) of your EXCEL workbook.
