This Bouncing Ball exercise uses the Tracker video analysis and modeling tool to explore the kinematics of a falling and bouncing ball. A bouncing ball video and worksheet answer key are included in this item. Numerous annotated screen-shots show how to use Tracker and how to use the Data Tool to curve-fit the ball's trajectory.
Please note that this resource requires
Quicktime, or
Xuggle.

in case you are wondering how to create a kinematic model for this case,
choose kinematics model add into y y = if (t < 0.68, -4.781*t^2+0.124*t+0.001, if(t < 1.48,-5.117*t^2+10.989*t-7.147,if(t < 2.04,-4.855*t^2+17.059*t-16.669,if(t < 2.44,-4.886*t^2+21.867*t-26.337,if(t < 2.78,-4.174*t^2+21.682*t-30.138,0)))))
all the coefficients of this model are read off from the data analysis coefficients from parabola fit y = a*t^2+b*t+c
enjoy! http://weelookang.blogspot.sg/2012/11/tracker-modeling-in-bouncing-ball.html the source trk edited with the new model can be download here http://www.phy.ntnu.edu.tw/ntnujava/index.php?topic=2620.0
classification should be a Motion in One Dimension instead :)

accessible from http://www.compadre.org/osp/document/ServeFile.cfm?ID=11705&DocID=2583&TrackerSet=1 within tracker under open the OSP Digital Library. Awesome feature
but classification should be a Motion in One Dimension instead :)
