A long thin straight stick is balanced on its end, on a flat horizontal frictionless surface (like an ice rink).
The balance is not quite perfect, so the stick slips / falls over. Clearly, its centre of mass will go in a vertical path down, to hit the surface at the point the stick originally stood on.
Question: Will the bottom of the stick leave the surface before the top of the stick touches it?
