Precession

I know it's not on the syllabus but one of my students wanted to do his IA on precession so thought I'd better brush up on the topic and what better way than to build a Geogebra simulation. The vectors aren't all to scale but I think it makes the point that the applied torque r ⊗ F causes a change in angular momentum that is in the same direction. You can try varying the angular speed of the disc, ω and the applied force, F.

Took me a couple of days but quite satisfying.
