I've been trying to implement these concepts into a computer program and I believe formula 8 is in error (and likewise formula 10 for similar reasons). The formula states two conditionals:

${\displaystyle {\begin{matrix}\mathbf {v} _{r}\cdot \mathbf {\hat {t}} =0&\mathbf {f} _{e}\cdot \mathbf {\hat {t}} \leq f_{s}\end{matrix}}}$

That doesn't completely make sense. The first half of that conditional should not be there. it is sufficient to state the second half only, which basically says, "if we are within the friction cone". 209.89.241.145 (talk) 04:49, 13 March 2015 (UTC)Reply

what if we get collision line, not point? How do we compute r1 and r2? — Preceding unsigned comment added by 89.178.72.172 (talk) 19:42, 27 November 2015 (UTC)Reply

Rigid or elastic body

Collision response#Rigid body contact states that the kinetic properties of the bodies are "depending on the elasticity of the materials", but "rigid bodies", as the name implies, have no elasticity 37.47.78.199 (talk) 12:43, 5 July 2023 (UTC)Reply

Reaction - Frictional force

In https://en.wikipedia.org/wiki/Collision_response#Frictional_force, the paragraph ends with, "The friction force can be calculated using the equation.". But which equation does this refer to? Does it refer to Equation 10 (at the bottom of the article)?
