Question

What is coefficient of friction? Write it's S.I unit.

Answer 1

This constant ratio is called the coefficient of friction and is usually symbolized by the Greek letter mu (μ). Mathematically, μ = F/L. Because both friction and load are measured in units of force (such as pounds or newtons), the coefficient of friction is dimensionless.

Answer 2

Explanation:

$ANSWER$

Coefficient of friction is defined as the ratio of the force required to move tow sliding surfaces over each other, and the force holding them together
