When an object with mass $m$ is lifted by a vertical distance $\Delta h$, its gravitational potential energy increases by $\Delta E_p$. The quantities $\Delta E_p$ and $\Delta h$ are connected by $\Delta E_p = mg\Delta h$, where $g$ is the acceleration of free fall. The definition of which physical quantity is required to derive this equation?
- Aacceleration
- Bmomentum
- Cpower
- Dwork done
