🥌 Curling Stone Curl: Pebbled-Ice Friction and Sweeping Lab

Throw a Blender-modelled curling stone and explore why it curls: speed-dependent pebbled-ice friction, a contact-ring friction model, spin, load asymmetry and the effect of sweeping, with live graphs and measured-versus-theory experiments.

⚙ Under the hood

A 19.96 kg granite stone slides on pebbled ice with speed-dependent friction; a 24-point contact-ring model produces the sideways curl of a rotating stone, and sweeping lowers friction. Experiments compare the simulation with the closed-form stopping distance and a first-order curl formula.
