"WebTo take into account the inertia of the pulley, still neglecting friction, we can take the tangential force on the pulley as m1g - m2g, or F = ( m1 - m2) g. This force, however, has to accelerate not only the pulley, but the masses, so we have F = ( m1 + m2) a + Frot. " - Inertia of pulley equation
