At the page http://www.lucamoroni.it/cdf-simulations/geogebra-basketball-3d there is a new Geogebra simulation named ** Basketball 3D**, illustrating the physics of a basketball shot

**.**

Here is a preview image

and a demo video:

This simulation could help students to playfully discover and experiment the properties of the parabolic motion and to understand the concept of flux of a vector field (*ball velocity*) through a surface (*the one delimited by the basketball ring*).

I made it also to explore the limits of what can be done with Geogebra in building a complex simulation and I’m rather impressed with the width of its opportunities, especially through the scripting and with its (rather hidden) potential.

**Note**: given complexity of the simulation it’s advisable to download the .ggb file and run it locally through the free *Geogebra Classic* desktop program. The web app may be rather slow and jerky.

The geogebra file can be downloaded in this page of the Geogebra material portal (link).

**Update June 2017**

A new version of the simulation with rebounds, allowing rimshots and bankshots, has been published here at the Geogebra material portal.
