Tiny collisions on the surfaces, called microwelds, cause friction.
There are irregularities on the surfaces of any material which might not be visible to the naked eyes. This rough surfaces causes friction between any two bodies.friction is caused by gravity pulling on one object making it "stick" to the other object.yo' momma!
how hard the surfaces push to gether the types of surfaces involved
Force pushing two surfaces together
two rough ones - there will be more friction xx

two rough surfaces
Yes, this is a true statement and causes friction.
The two groups decided to unite their efforts to achieve a common goal.
A cone has two surfaces.
erosion
temperature differences
Friction causes the molecules to vibrate faster, meaning that they produce more heat.
Gasket failure (they don't last forever). Warping of the two mating surfaces, loose bolts.
