Hi! Your app is very nice to describe the first and the second law, but it seems it's not working with the third law: the period is always 10 seconds.
Do you think it's possibile to fix this problem?
OK I fixed it, it has been simple, i just set the speed of the slider. You can see the code here: http://www.geogebratube.org/student/m32819
Here you can evaluate the period of the planets!
Bye
