Which equation most accurately expresses the quantitative relationship between the net force acting on a system and the system’s acceleration? (a)

\vec a=\dfrac{\sum \vec F}{m}+\vec g

(b)

\vec a=\dfrac{\sum \vec F}{2m}

(c)

\vec a=\dfrac{\sum \vec F}{m}

(d)

\vec F_{\text{net}}=m\vec a+m\vec g
