Roger,

The simulation makes for a good tutorial.

Here is another that may interest you.

Newton considered, as a thought experiment, a cannon ball fired from the top of a VERY high mountain. With ever increasing muzzle velocity he speculated that the canon ball would eventually circle the Earth, thus simulating the motion of the moon about the Earth.

(See: http://waowen.screaming.net/revision/force&motion/ncanon.htm) 

You might try  1/r, 1/r^2, 1/r^3 gravitational forces to see which produces the observed results.
