Abstract
GeoGebra is a free software which has wide possibilities of using at secondary schools. In math lessons it is obvious.
Using of GeoGebra for teaching the geometry and the analytical geometry is maybe an easiest way how to utilize this software. However, GeoGebra also offers tools for the calculus, the statistics and animations.
All these facts suggest that we can use GeoGebra in physics. We can work with coordinates and vectors, we can simulate physical systems which are depended on a time and show their evolutions through animations.
Then, using of the calculus and statistics in physics is a matter of course. We can also use interactive tools and create our own applets.
A great advantage of GeoGebra is that basic tools are intuitive and simple to use. Thanks to this fact GeoGebra has lots of users around all world and they share materials ready to use at schools or instructions how to use some certain tool.
This paper shows some of possibilities how to use GeoGebra at physics lessons.
