"Don't touch the ground" - the model of a bouncing ball

The GeoGebra model is fitted to the data obtained from videomeasurements of bouncing ball: https://www.dropbox.com/s/56a50hs9stbocgk/RedBall_Dionysis_x1_025.wmv?dl=0 To put your own data download ggb file. Next run the model in offline mode and create a new list of points. To make an effective control of the model look over: https://www.dropbox.com/s/2pmghhdg33tk708/DontTouch_optimization-01.mp4?dl=0 There are different methods of control depends on a magnitude sensitivity - compare action with a timeline: 00:00 - 00:07 control of Vx by mouse 00:10 - 00:28 control of Vy by mouse 00:30 - 00:50 control of Vx by hotkeys CTRL + <- or CTRL + -> 00:52 - 01:01 point at Vx' without action 01:03 - 01:08 control of Vy' by mouse 01:10 - 01:16 control of Vy; by hotkeys CTRL + <- or CTRL + -> 01:20 launch simulation 01:50 control of the bounce moment by mouse and the hotkeys
