Mathavan

- μs (ball-table sliding friction)
  Lower → topspin/backspin/corkscrew take longer to wear off and transition to natural roll.
- μw (ball-cushion friction)
  Lower → sidespin has less effect changing the rebound angle off the rail, and more sidespin remains on the cueball.

Stronge

- stronge_e_n (Normal restitution) — higher = springier cushion, less energy lost on direct impacts.
- stronge_μ (Cushion friction) — lower = slippery cushion, sidespin alters rebound angle less.
- stronge_omega_ratio (Stiffness ratio) — controls normal/tangential frequency ratio; higher = smoother, more delayed spin transfer.

Han

- muS (sliding friction) — controls how fast the cue ball "grabs" the cloth with spin.
- mu (rolling friction) — controls how quickly a rolling ball stops.
