Right! Squeak is a great place to model or even break the laws of physics.
Here is a great set of Squeak Etoys for NASA from physics professor Randy Caton

Etoys isn't the Smalltalk workspace, but the simple tile scripting language built into Squeak.
Here are more Etoys on physics, but you don't need to be a Squeak Central or NASA guru to make them, as I show in Free Fall.
