Homework Help: science

Posted by Luna on Thursday, December 9, 2010 at 6:56pm.

This isn't a homework/quiz question, Well I guess it is homework, But I need to find out three types of friction in a machine I just built, but I don't know any types of friction. So I was wondering if someone could list the types and explain what they are.
Thank you so so much if you answer this question! you're a lifesaver!
