Damping Force Constant Units

The damping force on an oscillator is directly proportional to the velocity. The units of the constant of proportionality are:

[2012 pre]

\(kg m s^{-1}\)

\(kg/ms\)

\(kg s^{-1}\)

\(kg s\)

Damping force \(F_d = -bv\). The constant \(b\) has dimensions \([F_d]/[v] = (MLT^{-2})/(LT^{-1}) = MT^{-1}\), which is \(kg s^{-1}\).
