[Physics] the name of the variable $b$ in the equation $F=-bv$

dragfrictionterminology

I saw that the equation F=-bv is used for the drag force for damped harmonic motion, where F is the drag force, v is the velocity of the hanging mass.

Question) What is the name for b though?

I saw that the value of b varies with fluid and dimensions of the object, but still can't find the exact name for that.

Best Answer

It is generally called the damping coefficient.
