Noob Question | Friction and Weight
In real life the more mass an object has, the more friction it has with the surface it's sitting on. Does Unity's physics engine reflect this? or is friction independent of mass?

"In real life the more mass an object has, the more friction it has" - that's not strictly true.... friction depends on the force exerted by each surface perpendicular to the other (which may depend on mass) and the coefficient of friction (i.e. the roughness) of the surface. To my knowledge, Physx reflects both of these factors.
I'm not good at physics, so correct me if I'm wrong... The more mass an object has, the stronger gravity acts on the object, the more force it exerts on the floor, the more friction it has against the floor, correct? I may have oversimplified a little too much in my original question.
And you say Unity does reflect this?
