Answer 2

Can't help you with a specific PC program. But there are a lot of this kind of things on the web. They are interactive; so you can see what happens if you change an input value. I found http://www.colorado.edu/physics/2000/index.pl, which is a cool interactive site, by browsing "physics demonstrations."
