A block of concrete weighs 20 kg, it takes 40 N to start the block sliding on a concrete floor and 10 N to maintain sliding. Calculate the Static coefficiant of friction and calculate the kinetci coefficiant of friction My question is; what is the coefficiant of static and kinetic friction. Ive read throught the book and cant seem to find anything that explains it. I found a formula which reads F = Static coefficiant multiplied by the weight of the block. But that doesnt tell me exactly what the coeffciant of each is, Is it a constant? or does it vary based on the item being moved? Thank you.
