Lab- Motion Graphs (Computer) Name_____________________ Per. ___

Background: There are basically 3 types of motion graphs.

Purpose: To gain a better understanding of the types of motion graphs by viewing animations of types of motion.

   and check out the concept of "relative motion". Be sure to check the "2D" box! (And on a final note: you can see Galileo's last 'statement' to the Roman Catholic Church if you go to http://www.jpl.nasa.gov/galileo/finger.html He gave them the ___________________!)
