Static/kinetic friction

Postby davidr » Mon Nov 23, 2015 8:34 am

A few questions:
It seems you can only give an object a general coefficient of friction, and not a kinetic and static friction coefficient, is this true? Also, say the coefficient of friction between 2 objects should be 0.7. Should I then enter 0.7 for both objects? What if the coefficients of friction for the 2 objects were different, would the coefficient of friction between them be the average of the two?
Thanks

As much as I know, friction works by multiplying both values with each other, so for 0.7 one of them should have 0.7, the other 1, or both have the square root of 0.7

There is no static friction in algodoo :(
Dream of Algodoo as game development engine...

You could use scripting to say that if math.vec.len(vel) <= 0.1, then friction = your value into the shapes, but a real static friction does not exist.

Q: What if the coefficients of friction for the 2 objects were different?
A: u = (u1 * u2)^0.5
