Question

write the si unit of co efficient of static friction ​

Answer 1

Explanation:

As we know the units of force are newton and normal is also a force, hence its unit is also newton. The two forces units will cancel each other. Therefore, the coefficient of friction has no unit. It is a unit less and dimensionless quantity.

Hope this helps you

Answer 2

Answer:

It is usually symbolized by the Greek letter mu (μ). Mathematically, μ = F/N, where F is the frictional force and N is the normal force. Because both F and N are measured in units of force (such as newtons or pounds), the coefficient of friction is dimensionless.
