edit:

i wont discuss that outlaw but then friction is surface INDEPENDENT for rigid objects as boxes and surface DEPENDANT for soft objects like tyres

so actually the right answer for my question:

is frictiion surface dependant?

the right answer is yes and no

edit:

otlaw your so gonna love this:

if i google:

3 point of contact friction

this thread makes it 7th of 5.400.000

so either google has me on high steem or this is not such widely known idea

YOU ARE BACK?!?!

haha ive just had a physics exam and one of the questions was sliding friction, i didnt mention the law of the 3 points of contact though so after 10 years im pretty sure finally im passing physics

Excellent. Snoopy and the Red Baron are back in action. Time for some more entertainment.
