What’s does “co efficient of friction” mean and how is it different from Friction Force?
In: 1
Ok so the coefficient of friction is the constant that relates the pressure force often weight with the friction force. So Ff ~ Fp this Fp is often just the weight of the object Fg=m×g, m is mass g = 9.8 m/s². This coefficient has information about how much friction is between the two surfaces. If the table is frictionless this coefficient is 0. Any greater than 0 and you got friction but this friction is proportional to this Fp. So its simply Ff = mu×Fp. If Fp=1N, measure the force of friction and that is going to equal mu. This coefficient has no dimension its just a number. If this coefficient is small you got a little amount of friction like ice, if its large Ff will be big like with sandpaper.
