The data came from my lab involving friction between wooden block with metal weight on it and a metal table. The wooden block is moved from rest and the force is measured using a force meter and Logger pro. 1. The problem statement, all variables and given/known data Force of peak static friction = 23.285N. Normal force is 20.567N u=F/N=1.132 2. Relevant equations Why is the coefficient of friction greater than 1? Several groups in my class also had similar results with u>1. Why is that? My guess is that there are some very small substance or agent between the wood block and table surface that is sticky and adds to friction force, or maybe there is magnetic force because there was a metal weight put on top of the wooden block to add more mass. Are my explanations plausible? Is there a better explanation?
